respectively. Complexes that contain a 3,3′,5,5′-tetrasubstituted dithiabiphenolate were prepared in a reaction between Mo(NAr)(CHCMe2Ph)(Me2pyr)2 (Me2pyr = 2,5-dimethylpyrrolide) and the 3,3′,5,5′-tetrasubstituted dithiabiphenols, (3,3′,5,5′-tetrachlorodithiabiphenol (H2Cl4S2), 3,3′,5,5′-tetrabromodithiabiphenol (H2Br4S2), and 3,3′,5,5′-tetra-t-Bu-dithiabiphenol (H2Bu4S2)). The isolated complexes include
Zn(DCTC)(DCTC = 3,6-dichlorodithiacatecholate)与Mo(NAd)(CHCMe 2 Ph)Cl 2(PPh 2 Me)(Ad = 1-金刚烷基)反应生成Mo(NAd)(CHCMe 2 Ph)( DCTC)(PPh 2 Me)。Zn(DCTC)与Mo(NAd)(CH- t- Bu)(OTf)2(dme)或Mo(NAr)(CHCMe 2 Ph)(OTf)2(dme)之间的反应(Ar = 2,6- i -Pr 2 C 6 H 3; OTf =三氟甲磺酸盐; dme = 1,2-二甲氧基乙烷)产生[Mo(NAd)(CH- t- Bu)(DCTC)] 2和[Mo(NAr)(CHCMe 2 Ph) (DCTC)] 2, 分别。在Mo(NAr)(CHCMe 2 Ph)(Me 2 pyr)2(Me 2 pyr = 2,5-二甲基吡咯化物)与M(NAr)(CHCMe
