摘要：

A general and new synthesis of hexacoordinate chiral 1-[2-methylallyl]Ru-II 2 complexes is presented. This synthesis uses the very accessible CODRu(2-methylallyl)(2) complex as starting material. These complexes (P*P)Ru(eta(3)-(CH2)(2)CCH3)(2) (e.g. P*P=DIOP, CBD, DEGUPHOS, BINAP, BIPHEMP, CHIRAPHOS, PROPHOS, DIMPC, BPPM, BDPP, DIPAMP, DIPAMPSi, beta-PO-OP) have been characterized spectroscopically. X-Ray structures were obtained for (S,S)-DIOP and (S,S)-CHIRAPHOS. They are suitable for the preparation of chiral dihalide ruthenium (II) catalysts. In addition, we have found that it was possible to prepare these same catalysts directly in situ from (COD)Ru(eta(3)-(CH2)(2)CCH3)(2) by adding 1-1.3 equiv. of the appropriate chiral ligand in the presence of HX in acetone at room temperature.
