摘要
2,2,2-Trifluoroethyldiphenylphosphine oxide [Ph2P(O)CH2CF3] (2) is known to give no Homer reaction product with enolizable aldehydes. We found, however, that some enolizable aldehydes such as N-Boc-pyrrolidine-2-aldehyde (9) gave the expected 3,3,3trifluoroprop-1-enyl compounds by reaction with 2. The products could be further transformed to some 2,2,2-trifluoroethyl-substituted nitrogen-containing heterocycles by using radical cyclization or Heck reaction. (C) 2004 Elsevier Ltd.
