✦ Synopsis

Titanocene-Catalyzed Cyclocarbonylation of o-Allyl Aryl Ketones to . gamma.-Butyrolactones.

-The first catalytic method for the formation of γ-butyrolactones from enones containing an arylketone moiety using Cp2Ti(PMe3)2 or Cp2Ti(CO)2 is developed. The mechanism of this catalytic hetero Pauson-Khand type process is discussed in terms of the formation of a charge transfer complex in the cycle.
