NOVEL NICKEL CATALYZED CONVERSATION OF 2-BROMO-1-PHENYL-1,3-BUTADIENE TO AN α KETO LACTONE. AN EXAMPLE OF DOUBLE CARBONYLATION OF A HALODIENE
Alper, Howard,Vasapollo, Giuseppe
, p. 2617 - 2618 (2007/10/02)
Nickel cyanide and phase transfer catalyzed carbonylation of 2-bromo-1-phenyl-1,3-butadiene affords an methylene-α-keto lactone in good yield; isomerization to a ketobutenolide occurs on silica gel.
