Abstract
Two key intermediates in the mechanistic cycle of cycloplatination of aryl oximes by PtII complexes were crystallographically characterized. trans‐[PtCl2(SOMe2)(N‐acetophenone oxime)] is an active precursor on the C–H cleavage reaction coordinate. The formation of trans‐[PtCl2(N‐benzaldehyde oxime)2] accounts for the rate retardation by excess oxime. DFT calculations support the crystallographic evidence that provides unequivocal proof for the electrophilic nature of cycloplatination. (© Wiley‐VCH Verlag GmbH & Co.
