Synthesis and characterization of asymmetric C,N-cyclometallated complexes of Mo(II). X-ray crystal structures of [η5-C5H5)MoC6H2-(OCH2O)-2,3-CH2NMe2-6(I)(NO)] and [(η5-C5H5)MoS-C6H4CH(Me)NMe2-2(I)(NO)]
摘要:
The reaction of {(eta(5)-C5H5)Mo(mu-I)(I)(NO)}(2)] with the Hg derivatives of substituted N,N-dimethylbenzylamines [Hg(Q dmba)(2)] (HQ = substituted N,N-dimethylbenzylamine affords the organomolybdenum complexes [(eta(5)-C5H5)Mo(Qdmba)(I)(NO)] (2a-2e) in nearly quantitative yield as a racemic mixture of both enantiomers. When the reaction is carried out with Hg{S-C6H4C(H)(Me)NMe(2)}(2), a 1:1 mixture of both diastereoisomers [(eta(5)-C5H5)Mo{S-C6H4C(H)(Me)NMe(2)-2}(I)(NO)] (2f-2g) is obtained. The resolution of this mixture can be accomplished by fractional crystallization in CH2Cl2/hexane. The X-ray crystal structure of the complexes (SPY-5-15-A,C)-[(eta(5)-C5H5)Mo{C6H2-(OCH2O)-2,3-CH(2)NMe(2)-6}(I)(NO)] (2b) and (SPY-5-15-C)-[(eta(5)-C5H5)Mo{S-C6H4C(H)(Me)NMe(2)-2}(I)(NO)] (2f) are reported.
