Problems solved by technology

Especially in the case of homoallyl halides, in addition to further decomposition and isomerization caused by hydrogen halides generated by the decomposition, there is a possibility that the polymerization of conjugated dienes generated by the decomposition may be rapidly initiated sex is extremely dangerous

Embodiment

[0036] Hereinafter, the present invention will be specifically described based on examples, but the present invention is not limited to these examples.

Synthetic example

[0038] Add 43.06g (0.50mol) of 3-methyl-3-buten-1-alcohol, 55.65g (0.55mol) of triethylamine, ether 200 g, and the temperature of the internal mixture was cooled to 5° C. while stirring. Then, 65.43 g (0.55 mol) of thionyl chloride was added dropwise over 2.5 hours while keeping the internal temperature at 10° C. or lower. After completion of the dropwise addition, it was heated to an internal temperature of 50 to 55° C., and heated and stirred for 13 hours. After cooling, 125 g of water was added, stirred, and left to stand, then the water phase was separated, and the organic phase was washed with 130 g of a 5% aqueous sodium bicarbonate solution and 125 g of water. 235.2 g of the separated organic phase were obtained, and the organic phase was analyzed by gas chromatography, and as a result, 46.5 g (0.44 mol; yield 88%) of 3-methyl-3-butenyl chloride were contained. The reaction liquid was distilled under reduced pressure to obtain 23.3 g of 3-methyl-3-butenyl chloride (he...

Abstract

A composition containing one or more types of basic compounds, selected from the group consisting of tertiary amines, nitrogen-containing heterocyclic aromatic compounds, alkali metal carbonates, alkaline earth metal carbonates, and alkali metal bicarbonates; and a homoallyl halide.

Description

technical field [0001] This invention relates to homoallyl halide compositions. Specifically, it relates to a composition containing a specific basic compound and a homoallyl halide. Background technique [0002] Homoallyl halides such as 3-methyl-3-butenyl chloride are used as raw materials for pharmaceuticals, compounds such as silane coupling agents, and resins. [0003] In general, halogenated hydrocarbons tend to decompose when exposed to heat, light, water, and the like. Especially in the case of homoallyl halides, in addition to further decomposition and isomerization caused by hydrogen halides generated by the decomposition, there is a possibility that the polymerization of conjugated dienes generated by the decomposition may be rapidly initiated Sex is extremely dangerous. [0004] Therefore, the produced homoallyl halide is usually used as a crude product as it is in the next step without separation and purification, or is processed as a dilute solution. [000...
