✦ Synopsis

I would like to report that vinylalanes react smoothly, conveniently and rapidly with aldehydes and ketones in ether-hydrocarbon or hydrocarbon solvents at room temperature to give the corresponding allylic alcohols. The reaction proceeds stereospecifically to give the trans ally1 alcohol as indicated by the 10.3~ out-of-plane CH bending band in the infrared and by the coupling constant (J=16 cps) of the olefinic protons in the nmr made clearly observable

The treatment of a variety of aldehydes and ketones with phenyl(tribromomethyl)mercury results in the production of carbon monoxide from the deoxygenation of the carbonyl group by dibromocarbene. Until now, reports of the production of carbon monoxide from the reaction
