Organometallic Imido Complexes - Highervalent Derivatives of the d-Metal Acids, 2[4]. - Alkyl-, Aryl-, and Cyclopentadienyl-Substituted Molybdenum(VI) and Tungsten(VI) Imido ComplexesCpMo(NtBu)2Cl (1a) and CpW(NtBu)2Cl (1b) (Cp = η5-C5H5) react with organolithium reagents to form alkyl and aryl complexes of the type CpMo(NtBu)2R 2a-4a and CpW(NtBu)2R 2b-4b, resp., (R = Me, CH2SiMe3, Ph), highly volatile organo-metallic compounds, which were isolated as analytically and spectroscopically pure oils by vacuum destillation. On the other hand, the protolysis reaction of 1a and 1b with excess of HCl gas affords monoimido complexes CpMo(NtBu)Cl3 (5a) and CpW(NtBu)Cl3 (5b), respectively.
