Substitution of THF by diorganylmethylthiboranes in (CO)5Cr · THF yields the rather unstable complexes (CO)5Cr · CH3SBR2 (R = CH3, C6H5). In contrast to the σ-thiophene complex (CO)5Cr · SC4H4 the pentacarbonylchromium complex of the σ-S-bonded 2-diethylboryl-5-methylthiopene is quite stable due to interaction of the boryl group with CO ligands.
在(CO)5 Cr· THF中用二有机基甲基噻喃酮取代THF会生成相当不稳定的络合物(CO)5 Cr·CH 3 SBR 2(R = CH 3,C 6 H 5)。与σ-噻吩配合物(CO)5 Cr·SC 4 H 4相比,由于硼基与CO配体的相互作用,σ-S键合的2-二乙基硼基-5-甲基噻吩的五羰基铬配合物非常稳定。

Tris(methylthio)borane displaces acetonitrile from (CH3CN)3Cr(CO)3 in dioxane and yields yellow, sublimable [tris(methylthio)borane]chromium(0) tricarbonyl in low yield. The structure of the compound is discussed on the basis of IR and NMR spectra.
