Reactions of Sodium Tetrahydroborate and Cyanotrihydroborate with Rhodium(I), (II), and (III) Systems in the Presence of Tertiary Phosphines

Abstract: The nitrogen atmosphere reactions of phosphine–Rh(I), Rh(II), and Rh(III) chloride systems with NaBH4 and NaBH3CN and also similar reactions of [RhCl(CO)2]2 in the presence of phosphines are reported. Among the interesting products formed in the various reactions are hydrido, tetrahydroborato, hydrido–tetrahydroborato and hydrido–cyanotrihydroborato complexes such as the highly unstable Rh(I) species Rh(BH4)(PPh3)2, the much more stable Rh(II) complex RhH(BH4)(o-tolyl3P), the Rh(III)–5-phenyl-5H-dibenzophospho… Show more

“…4) which occur at >2400 cm-', and involve double hydrogen bridges (13,14). Compounds containing monodentate BH, have been shown (15) to have ir bands at -2400-2250 cm-' and bands at -2380 cm-' have been observed (3) in the tetrahedral complex Co(BH,)(PPh,),.…”

“…The evidence for this is very strong. Thus, the ir spectra show no trace of the typical bridging B-H mode which normally occurs (4,15) in the range 1850-21 50 cm-'. Neither is the bridge expansion band which normally occurs (1 5) at 1300-1500 cm-I in the spectra of bidentate BH, complexes present in any of the spectra unless it is unusually sharp and lies directly under one of the Nujol peaks.…”
