Preparation of benzocyclobutenols by low temperature reaction of ketone enolates with benzynes
Tripathy, Sasmita,Reddy, Ranga,Durst, Tony
, p. 997 - 1002 (2003)
The reaction of benzynes, generated from halobenzenes with lithium tetramethylpipiperide (LTMP) at -40 to -78°C, with ketone enolates affords benzocyclobutenols in fair to good yields.
