[n-(C4 H9)4 N][ReOBr 4(OPPh 3)]与三齿席夫碱[HOC 6 H4 C(H)NC 6 H4 SH]的反应允许分离[ReOBr{η3-(OC 6 H4 C(H)NC 6 H4 S)}](1)。[n-(C_4H_9)_4N][ReOBr_4(OPPh_3)]与[HOC_6H_4C(H)NC_6H_4SH]和适当的苯乙醚的反应(C_6H_4X-4-SH)(其中X=H,Br,Cl,F和OCH_3)在甲醇-乙腈中用三乙胺处理,分离出一系列[ReO{η_3-(OC6H4C(H)NC6H4S)}(η1-C6H4X-4-S)](X=H(2)、Br(3)、Cl(4)、F(5)和OCH 3(6))。同样地,在类似的反应条件下,使用(C6 H4 X-4-CH 2SH)型的苄基配体(其中X=H、Cl、F和OCH 3)导致分离出一系列[ReO{η3-(OC 6 H4 C(H)NC 6 H4 S)}(η1-C6 H4 X-4-CH 2S)]型的双金属配合物(X=H(7)、Cl(8)、F(9)和OCH 3(10))。将适当的胺官能团引入单齿配体的取代基R中允许分离阳离子氧合铼(V)物质,即[ReO{η3-(OC 6 H4 C(H)NC 6 H4 S)}(η1-C5 H4 NH-2-S)][Br](11)。
The reaction of [n-(C4H9)4N][ReOBr4(OPPh3)] with the tridentate Schiff-base [HOC6H4C(H)NC6H4SH] allows for the isolation of [ReOBr{η3-(OC6H4C(H)NC6H4S)}] (1). The reaction of [n-(C4H9)4N][ReOBr4(OPPh3)] with [HOC6H4C(H)NC6H4SH] and the appropriate benzenethiol (C6H4X-4-SH) where X=H, Br, Cl, F, and OCH3in methanol–acetonitrile treated with triethylamine has led to the isolation of a series of rhenium complexes of the type [ReO{η3-(OC6H4C(H)NC6H4S)} (η1-C6H4X-4-S)] (X=H (2), Br (3), Cl (4), F (5), and OCH3(6)). Likewise, under similar reaction conditions, the use of benzylmercaptan ligands of the type (C6H4X-4-CH2SH) where X=H, Cl, F, and OCH3has led to the isolation of a series of rhenium complexes of the type [ReO{η3-(OC6H4C(H)NC6H4S)} (η1-C6H4X-4-CH2S)] (X=H (7), Cl (8), F (9), and OCH3(10)). The incorporation of the appropriate amine functionality into the substituent R of the monodentate ligand allows for the isolation of a cationic oxorhenium(V) species, namely, [ReO{η3-(OC6H4C(H)NC6H4S)} (η1-C5H4NH-2-S)][Br] (11).
