Abstract:
[CO(CO) 2 (R 2 PCH 2 ) 3 CCH 2 PR 2 ][CO(CO) 4 ] (R = C 6 H 5 ) was synthesized in a simple manner from Co 2 (CO) 8 and the tetratertiary phosphine C[CH 2 P(C 6 H 5 ) 2 ] 4 , which acts only as a tridentate ligand. [Co(CO) 2 (R 2 PCH 2 ) 3 CCH2PR2][Co(CO) 4 ] reacts with NH 4 PF 6 , NaBH 4 , NaBD 4 or liquid ammonia at 20 °C to [Co(CO) 2 (R 2 PCH 2 ) 3 CCH 2 PR 2 ]PF 6 , CoH(CO) 2 (R 2 PCH 2 ) 2 C(CH 2 PR 2 · BH 3 ) 2 , CoD(CO) 2 (R 2 PCH 2 ) 2 C(CH 2 PR 2 · BD 3 ) 2 or Co(CO)(CONH 2 )(R 2 PCH 2 ) 3 CCH 2 PR 2 . In liquid ammonia [Co(CO) 2 (R 2 PCH 2 ) 3 CCH 2 PR 2 ][Co(CO) 4 ] at 60 °C yields the hydride CoH(CO)(R 2 PCH 2 ) 3 CCH 2 PR 2 . The new compounds were characterized, as much as possible, by their IR, Raman and 1 H NMR data.
