Title:
PROCESS FOR PRODUCING ALLYL-SUBSTITUTED BISPHENOL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2016/175128
Kind Code:
A1
Abstract:
The present invention relates to a process for producing an allyl-substituted bisphenol compound, the process including a step in which a diallyl-etherified bisphenol compound represented by general formula (I) is caused to undergo thermal rearrangement in the presence of a phosphine compound represented by general formula (II). [In the formula, A represents a single bond, -SO2-, -S-, -O-, the divalent group represented by formula (i-1), or a divalent group represented by -CY1Y2- (wherein Y1 and Y2 each independently represent a hydrogen atom, a linear, branched, or cyclic, C6 or lower alkyl group, a phenyl group, or a C7-8 aralkyl group); B1 and B2 each independently represent a linear, branched, or cyclic, C6 or lower alkyl group, an allyl group, a phenyl group, or a C7-8 aralkyl group; and n1 and n2 each independently represent an integer of 0-2.] [In the formula (II), R1, R2, and R3 each independently represent a linear, branched, or cyclic, C6-10 alkyl group, a C6-14 aryl group, or a C7-8 aralkyl group.]
