Abstract
The mechanism of the title catalytic system was investigated, in particular by synthesizing several compounds that model the postulated metal-oxo-prop argyloxo intermediates, such as [Ti(mu-O)(O-Bu-t)(O(2)CTol)](2) (Tol = p-Me C6H4), Ti(OCMe2C=CH)(4) and [CuCl(Me2C(OH)C=CH)](4). The molecular structur e of [CuCl(Me2C(OH)C=CH)](4) was determined by; X-ray crystallography and h eterobimetallic Ti-Cu complexes comprising the 2-methyl-3-butyn-2-oxo fragm ent are reported.
