  1,6-Dihydro-1,6-disilapentalene derivatives by 1,1-organoboration of triynes

  摘要：

  The triynes (RC)-C-1=C-SiMe2-C=C-SiMe2-C=CR1 [R-1 = H (3), SiMe3 (4) SnMe3 (5)] were prepared, and their reactivity towards triorganoboranes R3B 6 [R = Et (a), CH2Ph (b), Ph (c), 2-thienyl (d)] was studied. In the case of 3, decomposition was observed whereas the reaction of 4 and 5 with 6 affords the 1,6-dihydro-1,6-disilapentalene derivatives 7a-d (from 4) and 9a, c (from 5) in almost quantitative yield. This is the result of stereo- and regioselective intermolecular 1,1-organoboration in the first step of the reaction, followed by two consecutive intramolecular 1,1-vinyloborations. The products were characterised by their H-1-,B- 11-, C-13-, Si-29- and Sn-119-NMR data. (C) 1998 Elsevier Science S.A. All rights reserved.
