We recently reported that mercuric trifluoroacetate was an effective catalyst for equilibrating carbamic esters of allylic alcohols at room temperature (1 8 3, X= NMe2). 394 Yields were uniformly high, and side-reactions (elimination, cyclization, &d sk2eta.l rearrangement) occasionally encountered
The Claisen rearrangement of ally1 vinyl ethers is catalyzed by PdCQ(CH3CN)Z. provided that alkyl substituents protect the vinyl ether double bond from coordination by the metal catalyst. [3,3]Sigmatropic rearrangements are very useful for the formation of C-C, C-O, C-N and C-S bonds. Besides the cl
