Abstract
Diethyl(prop-1-ynyl)borane 1 reacts, in the presence of a large excess of tetraethyldiborane(6), to give the new substituted 1-carba-arachno-pentaborane(10)4 as the first intermediate which can be isolated; 4 rearranges via the nido-C2B4(8) carbaboranes A and Bto the known pentaethyl-1,5-dicarba-closo-pentaborane(5)5which is characterized by single crystal X-ray analysis.
