Preparation of α‐Sulfonylethanone Oximes from Oxidized Hydroxylamine
Alkenes react with substituted N-hydroxysulfonamides and tetrabutylammonium periodate under metal catalyst free conditions to give oximes in good to high yields. The reaction proceeds in a one-pot manner, giving rise to the formation of intermolecular C–N and C–S bonds simultaneously. The method is mild, highly efficient, and convenient.
