Abstract

Abstract : Two (B-Cl)-chloroboroles form unsymmetric dimers which are highly fluxional in solution via reversible enantiomerisation through an intermediate with mirror symmetry. Abstract : The (B-Cl)-chloroboroles 2-chloro-1, 3-di(4-R-phenyl)-2, 4, 5, 6-tetra-hydrocyclopenta[ c ]borole (R = H, Br) undergo a novel dimerisation process in CH2 Cl2 solution. The resulting unsymmetric dimers are highly fluxional in solution via reversible enantiomerisation through an intermediate with mirror symmetry. DFT calculations suggest an unusual dimerisation mechanism and provide insight into the dynamics of the dimers.
