A novel, efficient and transition‐metal‐free alkylation of enol acetates by radical decarboxylation of N‐hydroxyphthalimide esters to synthesize α‐alkylated ketones in existence of Na2‐eosin Y at room temperature has been developed. This methodology features operational simplicity, mild reaction cond...
Some new N-substituted pyridazinones and triazolo[4,3-b]pyridazinones were synthesized, respectively, by simple alkylation and 1,3-dipolar cycloaddition of pyridazin-3-one with nitrile imines. The regioselectivity of the reactions was ascertained by 1H, 13C NMR spectroscopy and X-ray diffraction ...
