Steric limitations in associative substitution reactions of Os3(CO)9(mu-C4Ph4)
Reactions of the cluster Os3(CO)9(mu-C4Ph4) (1) with a large number of smaller P-donor nucleophiles (Tolman cone angle theta ? 143) proceed rapidly in heptane at room temperature via associative adduct formation to form the monosubstituted products. However, reactions with several larger P-donor nucleophiles (theta ? 145) in heptane at room temperature yield, in a single observable bimolecular step, a mixture of mononuclear and dinuclear products and it is therefore not possible to synthesize the monosubstituted clusters directly with these larger ligands. Crystallographic structures of Os3(CO)8(etpb)(mu-C4Ph 4)¡¤(CH3OH) (2etpb) (etpb = P(OCH2)3CEt) and Os3(CO)8-(P(OPh)3)(mu-C4Ph 4)¡¤(C6H14) (2P(OPh)3) have been determined and show that the substituent has displaced a CO ligand from the Os(CO)4 moiety in 1.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of Methoxydiphenylphosphine. In my other articles, you can also check out more blogs about 4020-99-9
