摘要

The β-keto phosphorus ylides (n-Bu) 3PCHC (O) Ph 6,(t-Bu) 2PhPCHC (O) Ph 7,(t-Bu) Ph2PCHC (O) Ph 8,(n-Bu) 2PhPCHC (O) Ph 9,(n-Bu) Ph2PCHC (O) Ph 10, Me2PhPCHC (O) Ph 11 and Ph3PCHC (O)(o-OMe-C6H4) 12 have been synthesized in 80–96% yields. The Ni (II) complexes [NiPh {Ph2PCHC (O)(o-OMeC6H4)}(PPh3)] 13,[NiPh {Ph (t-Bu) PCHC (O) Ph}(PPh3)] 15,[NiPh {(n-Bu) 2PCHC (O) Ph}(PPh3)] 16 and [NiPh {Ph (n-Bu) PCHC (O ...
