The rhodium(III)-catalyzed annulative coupling of 9-ben-zoylcarbazoles with internal alkynes proceeds efficiently through ortho CH and CN bond cleavages. This reaction provides direct access to variously substituted indanone derivatives. The carbazolyl leaving group can be readily recovered and reused for preparing the starting materials.

The Rh-catalyzed reaction of alkynes with 2-bromophenylboronic acids involves carbonylative cyclization to give indenones. The key steps in the reaction involve the addition of an arylrhodium(I) species to an alkyne and the oxidative addition of C-Br bond
1,1-Cycloaddition of oxalyl dichloride with dialkenylmetal compounds: Formation of cyclopentadienone derivatives by the reaction of 1,4,-dilithio-1,3-dienes or zirconacyclopentadienes with oxalyl chloride in the presence of CuCl
