Oxidation of alkynes and ylides by oxo(salen)chromium(V)(salen =N,N′-ethylenebis-salicylideneiminato) trifluoromethanesulphonate
Abstract
Oxo(salen)chromium(V) trifluoromethanesulphonate reacts with alkynes to afford diones, and with phosphorus ylides to afford aldehydes and ketones via similar organometallic intermediates.
