Condensation route from 1,1,1-tris(diethylboryl)propane to pentaethyl-1,5-dicarba-closo-pentaborane(5) via arachno-CB4(10) and nido-C2B4(8) carbaboranes.

Diethyl(prop-1-ynyl)borane reacts, in the presence of a large excess of tetraethyldiborane(6), to give the new substituted 1-carba-arachno-pentaborane(10) I as the 1st intermediate which can be isolated; I rearranges via nido-C2B4(8) carbaboranes to the known pentaethyl-1,5-dicarba-closo-pentaborane(5), II, which was characterized by single crystal x-ray anal.
