AbstractDouble hydroboration of acetylene, propyne-1 and t-butylacetylene with HBCl2 · OEt2/BCl3 leads to the 1,1-bis(dichloroboryl)alkanes 2d, e, f, in which halogen exchange is achieved by BI3 to give 3d, e, f. Redox reactions between butyne-2, hexyne-3 and 3 result in the formation of compounds 4, which are alkylated with AlMe3 and AlEt3 to give the pentaalkyl derivatives 1d, e, f. Reactions of 1 with [(C5H5)Co(C2H4)2] an [(C5H5)N iCO]2 lead to the complexes 5 and 6.
