Formation of carbonylrhenium cryptates with alkali metal cations: Coordination chemistry studies of [Ph2P(E)NP(E)Ph2]-, E = O, S, Se towards ReBr(CO)5
Reaction of ReBr(CO)5 with Li[Ph2P(O)NP(O)Ph2] afforded the cryptate Li[Re2(CO)6{µ-Ph2P(O)NP(O)Ph2- κ2O,O’}3]; whereas K[Ph2P(O)NP(O)Ph2] reacted with ReBr(CO)5 to give K[Re2(CO)6{ µ -Ph2P(O)NP(O)Ph2- κ 2O,O}{Ph2P(O)NP(O)Ph2- κ2O,O’}2]. Other chalcogen ligands’ salts M[Ph2P(E)NP(E)Ph2], E = Se and S...

| Sumario: | Reaction of ReBr(CO)5 with Li[Ph2P(O)NP(O)Ph2] afforded the cryptate Li[Re2(CO)6{µ-Ph2P(O)NP(O)Ph2- κ2O,O’}3]; whereas K[Ph2P(O)NP(O)Ph2] reacted with ReBr(CO)5 to give K[Re2(CO)6{ µ -Ph2P(O)NP(O)Ph2- κ 2O,O}{Ph2P(O)NP(O)Ph2- κ2O,O’}2]. Other chalcogen ligands’ salts M[Ph2P(E)NP(E)Ph2], E = Se and S, M = K and Li gave dirhenium carbonyls with bromido and Ph2P(E)NP(E)Ph2, E = Se or S bridges upon reaction with ReBr(CO)5. |
