  Ruthenium(II) complexes of 3,4-dimethylphosphacymantrene

  摘要：

  A series of RuCl2 complexes of 3,4-dimethylphosphacymantrene (L) have been synthesized. Their structures were established on the basis of H-1, C-13, P-31 NMR and IR spectroscopy. Two of them, trans-[RuCl2(L)4] and cis,cis,trans-[RuCl2(CO)2(L)2] were characterized by X-ray crystal structure analysis, and show the ligands L to bond via normal P-Ru sigma bonds, with Ru-P distances in the range 2.288(1)-2.339(1) angstrom.

  1,1′-Diphenyl-3,3′,4,4′-tetramethyl-2,2′,5,5′-tetrahydro-2,2′-biphosphole obtained by reductive dimerization of the appropriate phosphole has been converted into the corresponding 2,2′-biphosphole by P-bromination followed by dehydrobromination of the resulting P,P′-tetrabromo compound with α-picoline. This 2,2′-biphosphole gives two isomeric P-sulfides upon reaction with sulfur, and a Mo(CO)4 chelate

  3,4-Dimethylphosphacymantrene (1) reacts with tert-butyllithium to give the corresponding (η4-3,4-dimethyl-1-tert-butylphosphole)tricarbonylmanganate (2) which can act as a chelating ligand (L) toward a Pd2Cl2 dimeric core. The X-ray crystal structure of L2Pd2Cl2 (3) shows a bite angle of 60.5°.

• Recovering phospholes from phosphacymantrenes

  Several attempts to recover phospholes from phosphacymantrenes are described. UV irradiation gives 1,1'-biphospholes when the ring carries two phenyl substituents. Lithium reduction appears to give somewhat erratic results. E.-Co-attack by phenyllithium leads to eta (4)-anionic complexes derived from the corresponding 1-phenylphospholes. Quite surprisingly, this attack by phenyllithium is compatible with a carbonyl fonctionality on the ring. These anionic complexes yield eta (4)-phospholium derivatives upon quaternization of phosphorus with BrCH(2)CH(2)Z (Z = CN, COOEt). One of these phospholium complexes has been caracterized by X-ray crystal structure analysis. (C) 2001 Elsevier Science B.V. All rights reserved.
• Straightforward synthesis of phosphametallocenium cations of Rh and Ir

  Reaction of 3,4-dimethylphospholylthallium (Tl-1) with [Cp* MCl(2)](2) (M = Rh, Ir) leads to the formation of the dimeric species [(Cp* M)(2)(Me(2)C(4)H(2)P)(3)](+) 2 and 3 with bridging mu-eta(1): eta(1)-phospholyl ligands. The phosphametallocenium sandwich complexes [Cp* M(Me(2)C(4)(SiMe(3))(2)P)](+) 7 (M = Rh) and 8 (M = Ir) could be obtained from the reaction of [Cp* MCl(2)](2) and the 2,5-bis(trimethylsilyl)-1-trimethylstannylphosphole 6, with the bulky trimethylsilyl groups preventing the phosphole from eta(1)-and enforcing a eta(5)-coordination. The structures of phospharhodocenium cation 7 and a byproduct 9 containing a phosphairidocenium moiety could be determined by X-ray diffraction. (C) 2008 Elsevier B.V. All rights reserved.
