Abstract

Abstract Several optically active electron-rich olefins L 2★ have been prepared from readily available chiral starting materials, such as (S)-α-amino-acids (eg,(S)-leucine) or terpene derivatives (eg,(+)-or (−)-3-pinanecarboxylic acid). The derived carbene-transition-metal complexes (17 monocarbene Rh I, 1 bis (carbene) Rh I, and ad 8 Co complex) have been prepared with retention of optical integrity; some of their chemical and spectroscopic ...
