An aryl to imidoyl palladium migration process involving intramolecular C-H activation

Biologically interesting fluoren-9-one and xanthen-9-one derivatives have been prepared by a novel aryl to imidoyl palladium migration, followed by intramolecular arylation. The fluoren-9-one synthesis appears to involve both a palladium migration mechanism and a C-H activation process proceeding through an unprecedented organopalladium(IV) hydride intermediate. The results from deuterium labeling experiments are consistent with the proposed dual mechanism.

Thione S-Imides. The Reaction with Carbon-Hetero Atom Double Bond

9-Fluorenethione S-p-toluenesulfonimide reacted as a 1,3-dipole with imines, oximes, and thiones to form (3+2)cycloadducts, while with symmetrical azines and aldehydes, unsymmetrical azines, N-(p-tolylsulfonyl)imines and fluorenone were obtained as a result of the decomposition of the cycloadducts.
