Tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP): efficient catalysts for the cyanosilylation and cyanocarbonation of aldehydes and ketones.
A variety of aldehydes and ketones were transformed to their corresponding cyanohydrin silyl ethers in good to excellent yields in the presence of 1-5 mol% of tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP). Cyanohydrin carbonates were also readily prepared using 5-10 mol% of TTMPP as an organocatalyst.
