  Polarity reversal in η2-phosphinocarbene and η2-arsinocarbene complexes of tungsten

  摘要：

  Trichloro- and trifluoroacetic acids CF(3)COOh and CCl3COOH react with cationic eta(2)-phosphino-(Cp(CO)(PMe3)-W=C(R)-PPh2(BF4) as well as eta(2)-arsinocarbene complexes of tungsten (Cp(CO)(2)W=C(R)-AsPh2)(PF6) to form the corresponding eta(2)-phosphinomethanide (Cp(CO)(PMe3)(Y)W-C(H)(R)-PPh2)(BF4) (Y = CF3COO, CCl3COO) or eta(2)-arsinomethanide compounds (Cp(CO)(2)(CF3COO)W-C(H)(R)-AsPh2)(PF6), respectively. Next to spectroscopic investigations, the constitution of the new compounds is proved by X-ray single crystal structure determinations. (C) 1999 Elsevier Science S.A. All rights reserved.

  Cationic eta(2)-phosphinocarbene complexes [eta(2)-C5H5(CO)(PMe3)<(W = C(R)-P)over bar>Ph-2][PF6] (R = Me, Ph, Tol) react at -78 degrees C with alkyl isonitriles R'NC (R' = Me, Bu-t) to provide tungstaphosphabicyclo[1.1.0]butanone complexes [eta(5)- C5H5(R'NC)(PMe3)<(W-C(O)-C)over bar>(R)-PPh2][PF6] in high yields. The constitution of the yellow bicyclic compounds was determined by spectroscopic investigations and, in the case of the 4-methylphenyl substituted compound 2c, additionally by X-ray single crystal structure analysis. Crystal data for 2c are as follows: space group P2(1)/n (No. 14), a = 907.80(10), b = 3658.1(6), c = 1085.2(2) pm, alpha = 90 degrees, beta = 106.27(1)degrees, gamma = 90 degrees, Z = 4.
