Title:
NOVEL ACID HALIDE COMPOUND AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH0789921
Kind Code:
A
Abstract:

PURPOSE: To provide a novel acid halide compound useful for producing a 2-alkyl-2-propenoyl isocyanate useful as an intermediate for organic syhtheses, medicines and agrochemicals, and as a starting raw material for reactive polymer materials.

CONSTITUTION: An acid halide compound of formula I (R1 is 1-10C alcohol residue; R2 is H, 1-5C lower alkyl; X is halogen), e.g a compound of formula II. The compound of formula I is obtained by reacting a compound of formula III with a hydrogen halide of formula: HX 111 the presence of a compound of formula: R1 OH and subsequently reacting the reaction product with an oxalyl halide of formula: (COX)2. The compound of formula I is subjected to a thermal hydrogen halide-removing reaction in a highly concentrated homogeneous system to obtain a 2-alkyl-2-propenoyl isocyanate of formula IV. The novel acid halide compound of formula I has high solubility in general organic solvents.
