A novel strategy for the preparation of allylic phosphorus ylides directly from Morita-Baylis-Hillman (MBH) alcohols in an environmentally benign manner was developed. With the assistance of a calcium catalyst, the SN2′ process between phosphin

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.
