                                    The synthesis of new cyclic stannyloligosilanes [R2Sn(SiMe2)(n)] (2a, n = 5, R = Ph; 2b, n = 5, R = Me; 3a, n = 6, R = Ph; 3b n = 6, R = Me) is reported. The compounds are fully characterised by mass spectrometry and NMR spectroscopy and in the case of 2a also by X-ray analysis. (C) 1998 Elsevier Science S.A. All rights reserved.
