henry-reaction, Nitro-Aldol condensation

  The Henry reaction was first reported by Belgian chemist Louis Henry in 1895. The Henry reaction involves the addition of a nitronate salt to a carbonyl compound, usually an aldehyde. The reaction is also referred to as a Nitroaldol reaction. It is C-C bond-forming reaction used in organic synthesis.   Mechanism:   The Henry Reaction Mechanism can present in two steps … Read more

Aza-[2,3]-Wittig Rearrangement: Mechanism | Examples

The rearrangements reactions are important Name reaction in organic chemistry. Wittig rearrangement, first reported by G. Wittig and L. Löhmann in 1942, The Wittig rearrangement converts α-metalated ethers to metal alkoxides, yielding secondary or tertiary alcohols. Its nitrogen analog, the aza-Wittig rearrangement, transforms α-metalated tertiary amines into rearranged metal amides, producing homoallylic secondary amines. This … Read more
