Title:
SILACYCLOHEXANECARBALDEHYDE COMPOUND AND PRODUCTION OF SILACYCLOHEXANE-TYPE LIQUID CRYSTAL COMPOUND USING THE SAME
Document Type and Number:
Japanese Patent JPH07304780
Kind Code:
A
Abstract:
PURPOSE: To obtain a new compound useful as an intermediate for synthesizing liquid crystal compounds.
CONSTITUTION: The compound of the formula (Ar is phenyl or nitrile; R is an Ar, a 1-10C straight chain alkyl, a 3-8C branched chain alkyl or a 2-7C alkoxyalkyl), e.g. 4-n-pentyl-4-phenyl-4-silacyclohexanecarbaldehyde. The compound of the formula is synthesized by the following processes: a ylide compound formed from an alkoxymethyl triphenylphosphonium salt by the action of a base is subjected to Wittig rearrangement to produce an alkylphenol ether compound, which is then hydrolyzed with an acid catalyst.
