Abstract

Carbonyl coupling reaction employing low-valent titanium1 is a valuable method for preparing sterically hindered ole-Recently, McMurry and Krepski5 have demonstrated further that the method is equally effective for cross-couplings between aryl ketones and aliphatic carbonyl compounds. We investigated the cross-couplings between dicyclopropyl ketone and aliphatic ketones in the hope that heavily substituted cyclopropylethylenes ...
