Benzilic Acid Rearrangement. The benzilic acid rearrangement involves conversion of a 1,2-diketone into a carboxylic acid. The conditions are deceptively simple, hydroxide followed by an acid quench, and lead to the migration of a benzene ring. This mechanism is relatively straightforward.

The Sommelet-Hauser rearrangement may simply be defined as the rearrangement reaction of certain benzyl quaternary ammonium salts where the reagent used is sodium amide (or alkali amide) and the reaction results in the N,N-dialkylbenzylamine with a new alkyl substituent in the aromatic o-position. Now because the final product is a benzylic ...
Problem 1-11. All carbons are sp 2, and all bond angles are near 120°. Problem 1-12. All carbons except CH3 are sp 2. Problem 1-13. The CH3 carbon is sp 3; the triple-bond carbons are sp; the C≡C−C and H−C≡C bond angles are approximately 180°. Problem 1-14. (a) O has 2 lone pairs and is sp 3-hybridized.

Oct 17, 2011 · Introduction to Rearrangement Reactions. Reactions that involve a carbocation intermediate may be accompanied by rearrangements where a pair of electrons from a C-H or C-C bond migrates toward the carbocation, resulting in breakage and formation of a C-H or C-C bond, and formation of a new carbocation. The new carbocation (generally more stable ...
