Ni(II)-Mediated nitrosation of oximes bearing an α-CH2 group
摘要:
Heating of NiCl2 center dot 6H(2)O with 10-fold excess of an oxime having an alpha-CH2 group (1-4) at 100 degrees C for I day in air leads to the formation of the dioxime/ato complexes [Ni(dioxime/ato)(2)] (5-8) formed due to a novel type of metal-mediated nitrosation. Compounds 5-8 were characterized by elemental analyses, FAB (5-7) or APCI (8) mass-spectrometry, IR, H-1 and C-13{H-1} spectroscopies (for 8), and X-ray structural study has been performed for 5 and 8; the corresponding ketones (9-12) were identified by LC-MS.
