Reactions of coordinated ligands. VI. Reactions of cis-tetracarbonylbis-(chlorodiphenylphosphine)molybdenum(0) methylamine, p-toluidine, water, methanol, p-cresol, and ethanethiol and the subsequent reactions of the ammonolysis and hydrolysis products with chlorosilanes and boron trifluoride diethyletherate

  • The complex cis-[Mo(CO)4(PPh2Cl)2] (I) readily reacts with a variety of nucleophiles, HX where X NH2, NHMe, NH-p-C6H4Me, OCH3, O-p-6H4Me, and SEt, in the presence of a nitrogen base to yield new cis-[Mo(CO)4(PPh2X)2] complexes. The reaction of cis-[Mo(CO)4(PPh2NH2)2 (II) first with n-BuLi and then with dichlorosilanes yields unique heterocyclic complexes. The reaction of I with H2O and Et3N yields [Et3NH]+ cis-[Mo(CO)4(PPh2O)2H]- (VIII) which is postulated to contain a symmetrically-bound hydrogen. The hydrogen may be replaced by a BF2 group by treatment with BF3 · OEt2 and with a Na+ by treatment with NaOH and Et4NCl. Reaction of VIII with dichlorosilanes yields complexes containing unique heterocyclic rings analogous to those obtained from II.1H NMR and infrared spectral properties of the new complexes are given. © 1978.
