A highly basic phosphine, tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP), catalyzes trifluoromethylation using trifluoromethyltrimethylsilane to give the corresponding trifluoromethylated products in good to high yields, with both carbonylcompounds and imines.

Using (trifluoromethyl)trimethylsilane (TMSCF3) as the trifluoromethylating agent, MgCl2-catalyzed trifluoromethylation of carbonylcompounds proceeded readily at room temperature. In the presence of 10 mol% of MgCl2, a variety of carbonyl substrates such as aliphatic/aromatic aldehydes, acyclic/cyclic ketones and esters could be trifluoromethylated in DMF, giving the corresponding trimethylsilyl ethers
