Abstract

Abstract: The title compound 1 was prepared and converted into (+)-trans-dichloro-(trans-6, 7, lO, ll-tetrahydro-5H-benzocyclononene)((R)-c~-methylbenzylamine) platinum (II)(8). After fractional crystallization the platinum complex had [a]% f37. 4". Decomposition of the complex at-60" afforded optically inactive trans-olefin 1 sug-gesting that the trans-olefinic linkage in 1 is rotating very rapidly causing spontaneous racemization of olefin 1. The ...
