The preparation of organohaloboranes R3−nBXn (R = CH3, C2H5, C6H5; X = F, Cl, Br. I) by two convenient procedures is described. These are based on the action of boron halides on tetraorganostannanes and dialkylamino-organoboranes respectively.
描述了通过两种方便的方法制备有机卤代呋喃酮R 3- n BX n(R = CH 3,C 2 H 5,C 6 H 5; X = F,Cl,Br。I)。这些是基于卤化硼分别对四有机锡烷和二烷基氨基-有机硼烷的作用。

basicity of the sulfur atom in (CH3)2B-S-B(CH3)2 and (CH3)3Sn-S-B(CH3)2 leads to slow polymerisation of these compounds. (C6H5)2P-S-B(CH3)2 probably is a dimer with a six-membered B-S-P ring. [(CO)4Mn-S-B(CH3)2]2 is the first thermally stable transition metal complex of a boron-sulfurcompound. The Lewis acidity of the thio dimethylboranes is responsible for adduct formation with Lewis bases. Their Lewis
