(Chemical Equation Presented). The synthetic utility of chiral N-heterocyclic carbenes, which have been used mainly in transition metal-catalyzed reactions as a ligand, was demonstrated by the enantioselective acylation of secondary alcohols.

Thermal rearrangement of mono-, di-, and triphenyl-substituted ketene ethylene acetals was studied. Pyrolysis of all of these acetals provided phenyl-substituted tetrahydro-2-furanones as a major product. The more phenyl groups substitute on the ketene acetal skeleton, the lower reaction temperature was required for the rearrangement. In the cases of the diphenylketene acetals at high temperatures, fragmentation products, such as fluorene and benzophenone, probably derived from dipheylcarbene via diphenylketene, were observed.
