Dedicated to Professor Wolfgang Beck on the occasion of his 80^th birthday in recognition of his many contributions to inorganic and organometallic chemistry

Transmetallation and oxidative substitution were utilized to prepare examples of group 14, group 6 and group 10 complexes from lithiated or chlorinated 4,4-dimethyl-2-(2-thienyl) oxazoline or its N-alkylated analogs. Two of the product types (2 and 5) can be classified as α-thio or remote carbene complexes, depending on the position (3- or 5-) of attachment to the substituted thiophene ring. Spectroscopic measurements as well as crystal and molecular structure determinations clarified the bonding within the new compounds.

Key words: Carbene Complexes, Thienylidene Complexes, remote Carbenes, Chromium, Palladium
