Me (n = 4), Et (n = 3)) and RhCl(CO)(PEt3)2 with (trimethylsilyl)diazomethyl lithium at −78 °C in ether yields the three complexes Rh[C(N2)SiMe3](PEt3)3 (1), Rh[C(N2)SiMe3](PMe3)4 (2), and Rh[C(N2)SiMe3](CO)(PEt3)2 (3). 2 could not be isolated as a solid at room temperature but 1 was precipitated as red crystals that were stable enough to be handled under argon. X-ray work on 1 reveals a tetrahedrally

The C-F bond activation of fluoropyridines by [Rh(SiPh3)(PMe3)3] afforded Rh(I) fluoropyridyl complexes of the type [Rh(Ar(F))(PMe3)3] with concomitant formation of fluorotriphenylsilane; subsequent treatment with bis-catecholatodiboron yielded fac-[Rh(Bcat)3(PMe3)3] and the free fluoropyridyl boronate esters (Ar(F)Bcat).

The syntheses are reported of the rhodium(I) and ruthenium(II) trimethylphosphine complexes RhCl(PMe3)3, [Rh(PMe3)4]Cl, η5-C5H5Rh(PMe3)2, CHg6Rh4(PMe3)12, trans-RuCl2(PMe3)4, [Ru2Cl2(PMe3)8]Cl2, and [RuCl(PMe3)4]BF4 and of ruthenium(I), Ru2Cl2(PMe3)4; the structures of RhCl(PMe3)3 and [Rh(PMe3)4]Cl have been determined by single crystal X-ray analysis.

First examples of η5-1,2,4-triphosphacyclopentadienyl complexes of rhodium are reported and their structures, elucidated by 31P n.m.r. spectroscopy and X-ray diffraction studies, show interesting differences.
Treatment of [Rh(SPh)(PMe3)3], prepared in situ from [RhCl(PMe3)n(n= 3, 4) and NaSPh, with 1,2-bis(dimethylsilyl)ethane gave a mixture of cis,mer-[RhH2(SPh)(PMe3)3]1 and fac-[R[graphic omitted]Me2)H(PMe3)3]2; the structure of 2 has been determined by X-ray crystallography.
