Acetylenic acetals and ketals have been reacted with aryl and vinyl halides to generate hydroarylation and hydrovinylation products. The reaction proceeds with high regioselectivity. The carbopalladation step appears to be mainly controlled by stericeffects and the new carbon-carbon bond is generated preferentially on the carbon bearing the acetal group. The reaction has been employed to develop a

Described herein is a copper-catalyzed oxidative C–H annulation of quinolines with 1,2-chloroethane (DCE), providing a concise synthetic approach to benzoquinoliziniums. In this protocol, DCE not only serves as a solvent and an in situ activation agent of quinoline C2–H but also works as vinyl equivalents to constitute the six-membered azonia ring. Furthermore, the resultant benzoquinolizinium library
