Definitions

• the area of availability of the missing product is related to the chemical industry, and, more specifically, the method of radiation is 2-alkalis, or 2-odds,
• the indicated method is not intended for the use of multi-substituted 1,3-pandiands.

• the proposed method allows you to do differently 15 mono- and dialkyl substituted 1,3-industrial and to improve the technology of their emission.
• Metal hydride is mixed with metal halide, 20 as a part of which can be used with any suitable metal halide, but the metal ⁇ réelle None
• the resulting mixture adds a diluent - a simple solution, which can be consumed in water, for example, test-25, reagent, we can mix a mixture of diglyme and diethyl.
• Then add the alkyl- or dialkylalmal ether.
• the process is carried out at the boiling point of the boiling mixture of the reacting mixture at the time of stirring. At the end of the reaction, they separate the oily layer, the one layer extrudes 30 EHILIs. The essentials connect with the oil layer, wash and discard the air. Drop off the vacuum transfer and receive the target product.
• the cost of the target product is up to 92 weight (it’s not expensive). 35
• the proposed method is compared to a known method that allows the use of easy-to-use raw materials (alkyl and dialkyl-substituted small ones) - 3 - excludes the use of an active reagent and maldehyde, which causes irritation of the SLUISE compound.
• the proposed method is not known to result in not only dialkyl substituting 1,3- ⁇ andi-5, but not substituted.
• reaction mixture is heated while stirring at 70 ° ⁇ for 20 hours, it is allowed to cool and the mixture is stirred, and the mixture is stirred for 10 minutes. Separate the external organic layer, and wash the external layer 3 times for 30 ml of ethyl ether.
• Example 6 The process is similar to that described in Example 3. There are 40.4 g of methyl-ethyl ether. It takes a fraction of 90-98 ° C / 5 mm, while it is trapped in colorless crystals with a pressure of 40-4 ° C. The yield of 2-methyl-2-ethyl- ⁇ , 3-pandiopanadio 17.3 g (74, b%% theoretical). Example 6.
