摘要：

The cyclopropanation of alkenes with methyl diazoacetate in dichloromethane was catalyzed by rhodium(II) carboxylates containing a perfluoralkyl chain (Rh2L4, L = OOCC7F15 and OOC-C6H4-4-C6F13) The catalysts could be extracted into perfluoro(methylcyclohexane) and were reused several times without significant loss of activity. The same catalysts were used to achieve carbene transfer to toluene in the solvent system toluene-perfluoro(methylcyclohexane) at 60 degrees C. (C) 1999 Elsevier Science Ltd. All rights reserved.
