Title:
BUTYROLACTONE-COMPOUND PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/072365
Kind Code:
A1
Abstract:
Provided is a novel method for inexpensively producing, in high yield, a polymerizable compound useful for liquid crystal display elements. In this method for producing a compound represented by formula (3) (wherein n represents an integer in the range of 1-10), a compound represented by formula (1) (wherein: n is as described above; PG represents a C1-2 dialkyl acetal group, a 1, 3-dioxane group, or a 1, 3-dioxolane group; and Ar1 represents a biphenylene group or the like) is reacted with a compound represented by formula (2) (wherein R represents a C1-6 alkyl group), under acidic conditions, in the presence of a palladium catalyst and metallic tin or a tin-containing compound.
