2,3-Dichloro-5,6-dicyano-para-benzoquinone (DDQ)/methanesulfonic acid (MsOH)-mediated intramolecular arene-alkene oxidative coupling

An efficient intramolecular arene-alkene oxidative coupling of 1,4-diaryl-1,3-butadienes has been developed involving the use of a 2,3-dichloro-5,6-dicyano-para-benzoquinone (DDQ)/acid catalyst. The reaction involves the generation of a radical cation by abstraction of an electron from the substrate with DDQ, an intramolecular Friedel-Crafts-type reaction, and the loss of hydrogen radical.

The 'Silyl-Stobbe condensation' - Synthesis of fulgimides

Organooxyalkylation of 2,5-bis(trimethylsiloxy)-1-phenylpyrrole (1) with aromatic aldehydes 2 and acetone (5) is achieved to yield 2,3-bis[aryl(trimethylsiloxy)methyl]-N-phenylsuccinimides 4 and 2-[aryl(trimethylsiloxy)methyl]-3-[1-methyl-2-(trimethylsilo
