The direct observation of the naturally abundant 95Mo NMR spectra of [LMo(CO)3] (L = cycloheptatriene, mesitylene, o-, m-, and p-xylene, toluene, cyclopentadienyl anion) compounds are reported and discussed. Narrow resonances (Wh/2 ͌ 6 Hz) are observed, and the signals are the most shielded reported to date. The 95Mo NMR chemical shift is related to the molybdenum-arene bond strength for L = arene. Arene exchange between [LMo(CO)3] derivatives is not detected at 38 °C in dichloromethane. © 1981, American Chemical Society. All rights reserved.
