Title:
PROCESS FOR PRODUCING TERTIARY ALCOHOL HAVING ADAMANTANE SKELETON
Document Type and Number:
WIPO Patent Application WO/2002/002493
Kind Code:
A1
Abstract:
A process for producing a tertiary alcohol having an adamantane skeleton which comprises reacting optionally substituted 2-adamantanone with a Grignard reagent in the presence of a rare earth halide. By the process in which optionally substituted 2-adamantanone is alkylated to produce a tertiary alcohol, the addition product can be efficiently produced in high yield while almost perfectly inhibiting the generation of reduction products.
