Alkyl(carbazol-9-yl)(benzotriazol-1-yl)methanes are deprotonated by BuLi to form anions which react with alkyl halides, aldehydes, and isocyanates to afford the expected products and which add 1,4 to alpha,beta-unsaturated ketones. These products are hydrolyzed by dilute acid at ambient temperature to afford the corresponding ketones.
