Abstract
The rate-determining step of trityl-cyanoalkylidene condensation is th e interaction between the cyanoalkylidene derivative (CD) and the trip henylmethyl cation. The rate of the reaction follows first-order kinet ics with respect to both CD and the catalyst (Tr+) and is independent of the nature and concentration of the trityl ether. Glycosylation rat e constants have been determined for CD's of most common monosaccharid es.
