Sequential metal-halogen exchange reactions between n-C4H9Li and 1,3,5-tribromobenzene and reaction at each step with (CH3)3M^IVCl(M^IV = Si, Ge, Sn) has provided a 1,3,5-(trimethylmetal(IV))benzene compound.This class of compounds can be synthesized either trough a step-wise procedure, where the various intermediates are isolated, or in a continuous metal-halogen exchange process without isolation of various intermediates.
