The reaction between (NSCl)3 and gives together with Cl*CH2Cl2 (2) (characterised by X-ray crystallography, 31P n.m.r. and i.r. spectroscopy) and Ph3PNH (4).Reaction between (NSCl)3 and PPh3 also gives (2) and (4); a mechanism for this reaction is proposed.Reactions of (NSCl)3 with , trans-, or were investigated by 31P n.m.r. and contrary to several previous reports do not give thionitrosyl complexes but rather result in the formation of (2) and (4) or in the oxidation of the material to .The existence of any rhodium phosphine thionitrosyls is thus cast into doubt.

The nitrosyl complexes (M = Rh or Ir) react readily with trichloroacetic acid in acetone solution at ambient temperature to afford the dichloro-complexes in excellent yield.The rhodium-based reaction performed at ca. 0 deg C and quickly worked-up affords the carboxylate complex which is stable in pure acetone, but rapidly converts to the dichloride when free trichloroacetic acid and triphenylphosphine are introduced to the solution.The complexes , , mer-, and also react with trichloroacetic acid to form trichloroacetates which undergo similar ligand fragmentation reactions.Reaction pathways involving formation of CCl3(1-), Cl(1-), :CCl2, and CO2 fragments are outlined; hydrolysis of dichlorocarbene affords carbonyl ligands.Similar reactions have been observed with tribromoacetic acid.

The complexes 2 and 2 (S=CH2Cl2, THF) have been shown to react with CXCl3 (X=Cl, H) to form with generation of both dichlorocarbene and trichloromethyl radical.Reaction of 2 with CF3I, allyl- and benzyl-halides takes a different course giving organic coupling products and .The THF solvate complex also causes coupling of gem-dihalides, and dehalogenation of vic-dihalides to produce alkenes.Possible mechanisms for these reactions are discussed.

Attempts to prepare alkylidyne-trirhodium cluster complexes by reaction of Na with CX4, CHX3 (X = Cl or Br) and CCl3CF3 have resulted only in the formation of .With CHCl3 at -20 deg C the major product is 2, though to be formed by decomposition of .Reaction between Na and perfluoroacyl chlorides has given the new compounds F)(CO)2(PPh3)2> (RF = CF3, C2F5 and C3F7), which do not decarbonylate even after 6-9 days at 120 deg C.Tetrafluoroethylene has been found to react with under UV irradiation conditions to give in 33percent yield.The latter does not react with to form clusters, but surprisingly, its reaction with Na resulted in a low yield of CF3CCo3(CO)9; under similar conditions Na caused only decomposition.
