Transannularly bridged di-µ2-thiotetraborane(10). Dynamics, cis–trans-isomerism, reversible rearrangement: bis(diboranyl)‘butterfly’ structure
Abstract
B4H10 reacts with bifunctional thiols to give transannularly bridged H2(µ2)2S2RBH(B2H5) which exist as cis–trans isomers; on cooling these compounds rearrange to cis–trans H2B(µ2)2S2RB3H6.
