Abstract:
Reduction of [(OC) 3 CoPPh 2 ] n (1a ) with excess sodium granules affords [(OC) 3 CoPPh 2 ]Na 2 (3a) in solution as well as in solid state. However, in analogous reactions of [(OC) 3 CoPR 2 H] 2 (1b : R = C 6 H 11 ; 1c : R = t-Bu) with excess sodium granules the monovalent anionic complexes [(OC) 3 CoPR 2 H] Na (2b, c) are obtained in THF solution. 2b, c cannot be isolated in solid state. After removal of THF from their solutions the purified residues were identified by elemental analyses as [(OC) 3 CoPR 2 ]Na 2 (3b, c). Addition of buthyllithium to THF solutions of 3a, 2b, c gives rise to differently solvated complexes 3a*-c* which are transformed to [(OC) 3 CoPR 2 ]M 2 (M = N a, Li; 3 a′-c′). The course of the reactions and the products are controlled IR and 31 PNMR spectroscopically. 2b, c and 3a, b′, c′ were trapped with (H 3 CO) 2 SO 2 and CH 2 X 2 (X = Cl, I) yielding H 3 CCo(CO) 3 PR 2 H(6b, c), H 3 CCo(CO) 3 PR 2 CH 3 (4a - c ) and [xxx] (5a, b), respectively.
