Abstract

The reactions of Mo+ ions and Mo x O y + oxygen-containing molybdenum cluster ions (x = 1-3; y = 1-9) with methane, ethylene oxide, and cyclopropane were studied using ion cyclotron resonance. The formation of a number of organometallic ions, including the metallocarbene MoCH2 +, as well as molybdenum oxometallocarbenes Mo x O y CH2 + (x = 1-3; y = 2, 4, 5, or 8) and Mo x O y (CH4)+ ions (x = 1-3; y = 2, 5, or 8), was detected. The upper and lower limits of bond energies in oxometallocarbene complexes were evaluated: 111 > D 0 (Mo x O y +-CH2) > 82 kcal/mol (x = 1-3; y = 2, 5, 8).
