Single-crystal X-ray analysis of compound 2b reveals that the 18 chlorine substituents on the six silicons are symmetrically located on the outside. Compounds 2a,b reacted easily with methylinagnesium bromide in diethyl ether at room temperature to give hexakis[omega-(trimethylsilyl)alkyl] in high isolated yields of 93 and 94%.
