  Cyclic bis(amino)organotin cations, stabilized by π-coordination and new spirocyclic stannole derivatives

  摘要：

  The 1,1-organoboration of 2,2-di-1-alkynyl-1,3-di-tertbutyl-1,3,2-diazastannacyclohexanes (1) has been studied. Treatment of 1 with triethylborane (2) gave first a zwitterionic intermediate 6 in which a diamino(organo)tin cation is stabilized by side-on pi-coordination to the C=C bond of an alkynylborate moiety. The final products proved to be the spirocyclic stannoles 7. In the reaction between 1 and triisopropylborane (3) the intermediate of type 6 could not be detected, but the final product 8 has the same spirocyclic structure as 7. Multinuclear H-1, B-11, C-13, N-15 and Sn-119 NMR served for monitoring the reactions and characterization of intermediates and final products.
