The interaction of nitricoxide with peralkyl compounds of Zn, Cu, Re, Cr, Mo, W, and Zr and with the phosphine complexes Ni(η-C5H5)Me(PPh3), CoMe3(PMe3)3, and RhMe(PPh3)3, and RhMe(PPh3)3 has been studied. In addition to N-alkyl-N-nitrosohydroxylaminate, ON(R)NO, complexes normally formed from diamagnetic alkyls, and η2 or bridged nitrosoalkane, ONR, compounds usually obtained from paramagnetic alkyls

The synthesis of the new rhodium(I) complexes (Ph3P)3RhR (R = Me, Ph) is reported. The compounds react with phenol giving the new phenoxy derivatives (Ph3P)nRhOPh(n=2,3). Based on NMR evidence, a tetrahedral or trigonal pyramidal structure is proposed for (Ph3P)3RhMe. Upon heating, the latter one loses methane and it could be shown that the abstracted hydrogen comes from an orthoposition of one phenyl
