    • The complex Mo(CO)2(N2CH2SiMe 3)Cp shows a singlet at 2.92 ppm, and the complex Mo(CO) 2(N2C(H)(D)SiMe3)Cp shows a broad unresolved triplet at 2.90 ppm (in C6D6, However, analysis of these data required evacuation, which leads to some side products. Since N 2CHSiMe3 was added in hexane and the reaction done in heptane, NMR analysis required evacuation to dryness and redissolution in C6D6. During concentration some decomposition was observed to occur, particularly for Mo(CO)3(CH2SiMe 3)Cp. The alkyl product can react further with HMo(CO) 3Cp.31 (b) Jones, W. D, Bergman, R. G. J. Am.
