The synthesis of 1,3-butadien-2-ylcarbinols containing a tertiary alcohol is achieved by desilylation of (trimethylsilyl)methylallenic alcohols. The latter are obtained via a chromium-catalyzed addition of (4bromobut-2-ynyl)trimethylsilane to aliphatic or aromatic ketones. The desired adducts are ob
