** 1, 2-methyl-2-pentenal **
1. ** Using acronin and propyl Grignard reagents as raw materials **:
First, the Grignard reaction is carried out with acronin ($CH_2 = CHCHO $) and propyl magnesium bromide ($CH_3CH_2CH_2MgBr $). The negatively charged alkyl moiety ($CH_3CH_2CH_2 ^ - $) in the Grignard reagent attacks the carbon atom of the aldehyde group in the acronin, and a nucleophilic addition reaction occurs to form an alkoxy magnesium salt intermediate. After acid hydrolysis, the oxygen atom binds to the hydrogen ion to obtain 2-methyl-2-pentenol ($CH_3CH_2CH_2C (OH) (CH_3) CH = CH_2 $). Finally, using a suitable oxidant, such as manganese dioxide ($MnO_2 $), selectively oxidize the alcohol hydroxyl to an aldehyde group to obtain 2-methyl-2-pentenal ($CH_3CH_2CH_2C (CH_3) = CHCHO $).
2. ** Through the condensation reaction of aldol **:
Using propionaldehyde ($CH_3CH_2CHO $) Under the action of basic catalysts (such as sodium hydroxide aqueous solution), the α-hydrogen atom of the aldehyde group has a certain acidity and will leave in the form of protons to form enol negative ions. The enol negative ion reacts with the carbonyl group of another molecule of propionaldehyde to form β-hydroxyaldehyde intermediates. Under heating conditions, β-hydroxyaldehyde undergoes an intramolecular dehydration reaction to eliminate a molecule of water to obtain 2-methyl-2-pentenal.
** di, 6-bromo-1-hexanol **
1. ** Using 1,6-hexanediol as raw material **:
1,6-hexanediol ($HOCH_2 (CH_2) _4CH_2OH $) with an appropriate amount of hydrobromic acid ($HBr $) Substitution reaction occurs in the presence of catalysts such as sulfuric acid. Since the alcohol hydroxyl group can be replaced by a bromine atom, the reaction conditions are controlled so that one of the hydroxyl groups is replaced by a bromine atom to generate 6-bromo-1-hexanol ($BrCH_2 (CH_2) _4CH_2OH $). During the reaction, sulfuric acid plays a role in promoting the ionization of bromine ions by hydrobromic acid and enhancing its nucleophilicity, which is conducive to the substitution reaction.
2. ** Using cyclohexene as the starting material **:
First, cyclohexene ($C_6H_ {10} $) reacts with hydrogen bromide ($HBr $) in the presence of peroxide to form 1-bromocyclohexane ($C_6H_ {11} Br $). 1-bromocyclohexane is eliminated under basic conditions, such as co-heating with an alcohol solution of sodium hydroxide, to form cyclohexene. Then cyclohexene is reacted with reagents such as hydrogen peroxide and formic acid to carry out an epoxidation reaction to form epoxycyclohexane. Under the action of hydrobromic acid, the ring of epoxycyclohexane is opened, and bromine atom and hydroxyl group are added to the ends of the epoxy bond break, respectively. The reaction conditions are controlled, and 6-bromo-1-hexanol can be obtained.

Let's talk about 2-%E5%96%B9%E5%95%89%E7%94%B2%E9%86%9B first, in the way of medicine, it has a unique use. It can be used as medicine to treat certain diseases and diseases. Doctors use it as a guide, or it can help the medicinal power to reach the viscera, remove evil and help the upright. In the art of alchemy, it also has a wonderful effect, or it can reconcile various medicines, making the medicinal pill more effective. When it becomes a pill, the color is better and the medicinal power is purer.
Let's say 6-%E6%B0%9F-%E5%9C%A8, in military defense, it can make exquisite mechanisms. Integrating it into the defense system of the city wall can set up a clever trap, making it impossible to prevent the enemy from invading. In the construction of houses and buildings, it can be used to strengthen the structure, making the pavilion more stable and not falling down after wind and rain. In water conservancy projects, it can help water flow and be cleverly arranged according to the terrain, so that the irrigation water can enter the field evenly and ensure a bumper crop.
In the field of utensils manufacturing, 2-%E5%96%B9%E5%95%89%E7%94%B2%E9%86%9B can improve the quality of utensils, making utensils more tough and durable. 6-%E6%B0%9F-%E5%9C%A8 can give utensils unique functions, such as making boxes that can be opened and closed automatically, which are exquisite.
In terms of arithmetic deduction, the two may also have their symbolic significance and function, which can provide the deductor with unique ideas and insight into the secrets of heaven.
The two of them, in many fields such as medicine, alchemy, military, construction, water conservancy, artifact manufacturing, magic, etc., have each exerted their own abilities, bringing many conveniences and wonderful changes to the world.

Today, there are 20% of the city's total Yang Jia, and 60% of the city's total. However, the situation has not been studied, and the situation has not been determined. The nature of the square armor, its use, and the location of the place are all involved. If its nature is rare, it is used for rare stones or skillful crafts, and it is remote and remote, and it is not expensive to gather it. On the contrary, if the nature is common, use it. Strange and strange, and the ground is made of cloth, and it is difficult or flat.
The same is true for 60% of the total. There are many kinds of materials, and the uses are different. If it is necessary for people's livelihood, and the amount is limited, plus it is difficult and hidden, it will be self-elevating. If the use is ordinary, the source is wide, and it is easy to obtain, it will not be proud.
Moreover, the quality of the market is not due to the nature of the product itself, and the supply and demand, and the situation of the situation, have an impact. If the demand for a product increases greatly, but the supply does not demand it, it must be reduced; if the demand is reduced, the supply and demand will be low. Sixty percent of the total is the same, and every time the situation is difficult, the logistics will be blocked, or it will be normal; if the world is safe, the business will be convenient, or it will be determined.
In order to know the market of 20% of the total and 60% of the total, it is necessary to consider the nature, use, location, supply and demand of the product, and the general factors of the situation. Only when combined can we obtain the best.
