Modified Wittig| Wittig-Horner| Schlosser modification | Nucleophilic Addition to Carbonyl - Part 22

Описание: Among the two modifications of Wittig discussed herein, the first one is the Wittig-Horner reaction, and the second one is the Schlosser modification. The first modification can eliminate the disadvantage of the insolubility of the side product (phosphine oxide), and the second one enables the selective formation of E-alkenes.

Important books to be followed: Peter Sykes; Graham Solomons; Clayden, Greeves, Warren & Wothers; Carey, Sundberg.
