Efficient carbon-carbon bond formation with thermally stable 1,1-dihalo-2,2,2-trifluoroethylzinc reagent

Efficient carbon-carbon bond formation with thermally stable 1,1-dihalo-2,2,2-trifluoroethylzinc reagent. Fujita, Makoto; Morita, Tomoe; Hiyama, Tamejiro (Sagami Chem. Res. Cent., Sagamihara 229, Japan). Tetrahedron Lett.There are some reagents with their cas registry numbers 6287-38-3 and 354-48-3 are used in this study., 27(19), 2135-8 (English) 1986. CODEN: TELEAY. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 21 (General Organic Chemistry) The zinc carbenoids CF3CS2ZnX (X = halo), prepd. from CF3CS3 and Zn powder in DMF, were found thermally stable to add to aldehyde carbonyls in excellent yields. Thus, Zn powder was added portionwise to a soln. of BzH and Cl3CCF3 in DMF at room temp. and the mixt. stirred for 3h at 50° to give 86% HOCHPhCCl2CF3. .
