Metal complexes-catalyzed hydrolysis and alcoholysis of organic substrates such as alkenyl esters, alkenyl ethers, and azlactones (oxazol-5(4H)-ones) are described. These reactions were applied for kinetic resolution of chiral compounds and high selectivities were achieved with vinyl ethers of 2-substituted cyclohexanols, 1,1′-bi-2-naphthols, 1,1′-bi-2-phenols, and 4,4-disubstituted azlactones. Oxidative carbon-carbon bond cleavage reactions, which were found in the course of the study of asymmetric hydrolysis were also described.

Stereoisomers of 9-substituted selenoxanthen-10-io(alkoxalyl alkoxycarbonyl)methanides were prepared from the corresponding selenoxides and activated acetylenes.In the reaction of 9-phenylselenoxanthene 10-oxide(1c) with methyl propiolate afforded an unexpected product, methyl 9-phenylselenoxanthen-9-ylpropiolate(5) together with ylide(2e).The selenonium ylides underwent new reductive cyclization with sodium borohydride to afford new cyclic selenonium ylides.
