A photoinduced dehydrogenative homocoupling reaction of alkylarenes is reported. Gaseous hydrogen is evolved as the sole byproduct and neither oxidants nor hydrogen acceptors are required. The present reaction offers an environmentally benign and atom-economical means for forming sterically strained C-C single bonds. It also gives a remarkable example of photodriven reactions overcoming a considerable rise in energy.

We present a novel three-step protocol for preparing xanthene/thioxanthene and dibenzothiepine/dibenzoxepine from readily available starting materials. The Mizoroki-Heck cyclization as the final step was optimized to afford full conversion of the corresponding diaryl (thio)ethers and furthermore to achieve reasonably good selectivity between the 6-exo and the 7-endo products.

(Chemical Equation Presented) The oxidation of monoalkyl 2-(9H-xanthenyl)malonates 1 with Mn(OAc)3 gave the 9- or 10-dibenz[b,f]oxepincarboxylates 2 in good yields. The reaction proceeds with high regioselectivity except for the case of (1-meth
