Reactions of bis(trimethylsilyl)amine and -amide with MoOCl4

Dibenzoazepine hydrazine is a building block for N-alkene hybrid ligands: exploratory syntheses of complexes of Cu, Fe, and Li

“…Also 7 and 8 were tried in reactions with CuCl in a bid to obtain the copper amide via salt metathesis or under the elimination of TMSCl, respectively. 37 The reactions with 7 in varying metal to ligand ratios (cuprates were also envisioned) resulted in untractable mixtures, 38 while 8 did not react with CuCl even at 70 °C. The reaction of 9 with [CuMes] 4 results in dark brown reaction mixtures that show no 1 H NMR signals, indicative of a disproportionation reaction to metallic copper and a Cu( ii ) complex 15 (eqn (1)), 39 which was confirmed by single crystal X-ray diffraction analysis (Fig.…”

Reactions of MoOCl4 with 1-Methylimidazole, 1,4-Diaminobutane, 2-Methylpyridine, 2-Methylpiperidine, Trimethylsilylimidazole and 1-Methylpyrrolidine

“…There is N-H stretching at 3283 cm -1 in 4-methylpiperidine [23][24][25][26] . Stretching at 3152.7 cm -1 in [4], 3088.7 cm -1 in [5] and 3088.7 cm -1 in [6] suggest presence of N-H group in these compounds. Decrease in frequency is due to coordination of N-H group through nitrogen atom in these compounds.…”

“…Decrease in frequency is due to coordination of N-H group through nitrogen atom in these compounds. Stretching at 980.8 cm -1 , 975.8 cm -1 and 979.2 cm -1 in [4], [5] and [6], respectively, refer to Mo=O 16,17 group in terminal position (Table 5).…”

“…On comparison of NMR of 4-methylpiperidine 41 in solvent CDCl 3 with that of [4], [5] and [6] (Table 11), it is found that all peaks in these compounds except that of CH 3 have shifted downfield.…”

“…Reactions may yield addition, substitution, reduction, rearrangement and polymerization products. Reactions of MoOCl 4 in solvent CH 2 Cl 2 have been reported [1][2][3][4][5] by the author. Ligands are poorly soluble in solvent CH 2 Cl 2 so reactions of MoOCl 4 were also carried out and reported [6][7][8][9][10][11] by the author in CH 3 CN medium.…”
