Intermolecular addition reaction to alkenes of acylmolybdenum complexes generated by oxidative addition of aryl or alkenyl halides with molybdenum(0) carbonyl complexes
Acylmolybdenum species, generated by oxidative addition of aryl or alkenyl halides with molybdenum(0) carbonyl complex followed by carbon monoxide insertion, added to various kinds of alkenes intermolecularly to give simple addition products in good yields without formation of carbonylative Heck-type products.

Synthesis of 1,4-dicarbonyl compounds and 4-keto pimelates by palladium-catalyzed carbonylation of siloxycyclopropanes
Palladium-catalyzed reaction of a siloxycyclopropane with an aryl triflate under carbon monoxide pressure (10-20 atm) in HMPA and that with carbon monoxide in chloroform provides new synthetic routes to 1,4-dicarbonyl compounds and 4-keto pimelates, respectively. The reaction of a siloxycyclopropane with a vinyl triflate, on the other hand, gives an acyloxycyclopropane instead.
