The cleavage of a CC double bond after chemical ionization with NO+A complex rearrangement process1
摘要:
AbstractThe fragmentation of alkenes after chemical ionization with NO+, involving cleavage of the double bond, has been elucidated by deuterium labelling.
Rhodium‐Catalyzed Alkylation of C−H Bonds in Aromatic Amides with Non‐activated 1‐Alkenes: The Possible Generation of Carbene Intermediates from Alkenes
The alkylation of C−H bonds (hydroarylation) in aromatic amides with non‐activated 1‐alkenes using a rhodium catalyst and assisted by an 8‐aminoquinoline directing group is reported. The addition of a carboxylic acid is crucial for the success of this reaction. The results of deuterium‐labeling experiments indicate that one of deuterium atoms in the alkene is missing, suggesting that the reaction does

The Rh(I)-catalyzed ortho-alkylation of benzenesulfonamides with alkenes with the aid of an 8-aminoquinoline directing group is reported. The reaction is applicable to a variety of benzenesulfonamide derivatives and various alkenes. Curiously, unactivated 1-alkenes were more reactive than activated alkenes. Deuterium labeling experiments indicate that an unusual 1,2-H shift mechanism to generate a
