DIALKYLATION OF ACETOPHENONES AND ACETOPHENONE ETHYLENE KETALS WITH 1,8-BIS(TRIMETHYLSILYL)-2,6-OCTADIENE (BISTRO) - SEMIEMPIRICAL SCE STUDIES OF ALPHA-METHOXY-ALPHA-METHYLBENZYL CATIONS

Titanium tetrachloride mediated dialkylation of acetophenones or aceto
phenone ethylene ketals by 1,8-bis(trimethylsilyl)-2,6-octadiene (BIST
RO) leads to a mixture of dl and meso 1-alkyl-1-phenyl-2,5-divinylcycl
opentane. Better yields are observed with p-bromoacetophenone and m-me
thoxyacetophenone. (C) 1998 Elsevier Science Ltd. All rights reserved.
