  摘要：

  The new alpha,omega-[phosphanyl(organyl)]borane Me(2)PCH(2)B(NMe(2))(2) (8) was obtained in good yield by the reaction of ClB(NMe(2))(2) with LiCH(2)PMe(2). Compound 8 forms the transition metal complexes [(CO)(5)Cr{Me(2)PCH(2)B(NMe(2))(2)}] (9), [(MeC(5)H(4))Mn(CO)(2){Me(2)PCH(2)B(NMe(2))(2)}] (10), and [(CO)(4)Fe{Me(2)PCH(2)B(NMe(2))(2)}] (11), which were isolated as highly volatile liquids in high yields. Complex 11 easily underwent exchange reactions of the Me(2)N substituents which led to derivatives with threefold coordinated boron such as [(CO)(4)Fe{Me(2)PCH(2)B(OMe)(2)}] (13), and [(CO)(4)Fe{Me(2)PCH(2)B(NMe(2))Cl}] (14), or to a compound with tetrafold coordinated boron, [(CO)(4)Fe{Me(2)PCH(2)BCl(2)(NHMe(2))}] (15). Li[(CO)(4)Fe(Me(2)PCH(2)BH(3))] (16), cis,trans-[{(CO)(4)Fe(Me(2)PCH(2)BH(2))}(2)] (17), and [(CO)(4)Fe{Me(2)PCH(2)BH(2)(2,4,6-Me(3)C(5)H(2)N)}] (18) were obtained from 13 by corresponding substitution of the MeO groups. The addition of HSiPh(3) to the iron center was achieved by photolysis of 13, giving [(CO)(3)FeH(SiPh(3)){Me(2)PCH(2)B(OMe)(2)}] (19). [(CO)(5)Cr{Me(2)PCH(2)B(OMe)(2)}] (12), the chromium analogue of 13, was obtained from the reaction of [(CO)(5)Cr{Me(2)PCH(2)B(NMe(2))(2)}] (9) with MeOH. The structure of compound 19 was determined by single crystal X-ray diffraction. (C) 1997 Elsevier Science S.A.
