Abstract

Graphical abstract Reaction of ReBr(CO) 5 with Li[Ph 2P(O)NP(O)Ph 2] afforded the cryptate Li[Re 2(CO) 6{μ-Ph 2P(O)NP(O)Ph 2-κ 2 O,O′} 3]; whereas K[Ph 2P(O)NP(O)Ph 2] reacted with ReBr(CO) 5 to give K[Re 2(CO) 6{μ-Ph 2P(O)NP(O)Ph 2-κ 2 O,O′}{Ph 2P(O)NP(O)Ph 2-κ 2 O,O′} 2]. Other chalcogen ligands’ salts M[Ph 2P(E)NP(E)Ph 2], E = Se and S, M = K and Li gave dirhenium carbonyls with bromido and Ph 2P(E)NP(E)Ph 2, E = Se or S bridges upon reaction with ReBr(CO) 5.
