Direct C-H Functionalization of Phenanthrolines: Metal- And Light-Free Dicarbamoylations

A direct method for C-H dicarbamoylations of phenanthrolines has been developed, which is capable of directly installing primary, secondary as well as tertiary amides. This is a significant improvement on the previous direct method, which was limited to primary amides. The metal-, light-, and catalyst-free Minisci-type reaction is cheap, operationally simple, and scalable. We demonstrate that the step efficiency toward dicarbamoylated phenanthroline targets can now be significantly improved.

Cyclic esters of 3,4-dihydroxy-thiophene-1,1-dioxide compounds and 3,4-dihydroxy-cyclopentadienone compounds

Cyclic esters of 3,4-dihydroxy-thiophene-1,1-dioxide and of the corresponding cyclopentadienone compound, and their manufacture. The compounds can be used as "solid forms" of phosgene, thiophosgene or oxalyl chloride, or as acyl transfer agents.
