Abstract

Cyclotrimerization of t-butylacetylene or phenylacetylene with CpCo (CO) 2 as catalyst in supercritical water yields the isomeric 1, 3, 5-tris-substituted-(1: R= Ph, 1a: R= but) and 1, 2, 4-tris-substituted benzene derivatives (2: R= Ph, 2a: R= but). The identification of the organometallic products obtained under these conditions is described. The formation of all possible isomers of the corresponding CpCo (bis-substituted-cyclobutadiene)(3, 4), CpCo ...
