摘要：

Reaction of hexakis[2-(dimethylaminomethyl)phenyl]cyclotrisilane (1) with isocyanates results in the clean formation of cyclic di- or trisiloxanes 3 and 4a and the corresponding isonitrile. Single-crystal X-ray analysis tetrakis[2-(dimethylaminomethyl)pheny]cyclodisiloxane (4a) reveals each silicon center to interact with two amino groups forming Si ... N distances, which differ significantly in length. Phenyl isothiocyanate reacts with 1 with transfer of sulfur to yield pentacoordinated bis[2-(dimethylaminomethyl)phenyl]silane (11).
