Abstract
Abstract The cycloisomerization of 1,1,2,2-tetramethyl-1,2-divinyldisilane ( 1 ) in the presence of ruthenium–diphosphine complexes has been examined. A ruthenium–dppe ( 8 ) or a ruthenium–dppv ( 12 ) complex selectively catalyzed the reaction and 1,1,2,3,3-pentamethyl-1,3-disilycyclopent-4-ene ( 3 ) was isolated as the major product. The reaction was also carried out in the presence of a deuterated ruthenium–P i Pr 3 complex and the incorporation of deuterium to 1,1,4,4-tetramethyl-1,4-disilacyclohex-2-ene ( 2 ) was observed. The mechanism of this reaction has been proposed.
