Direct Electrophilic Diamination of Functionalized Alkenes without the Use of Any Metal Catalysts
摘要:
A new direct electrophilic diamination reaction of alpha,beta-unsaturated ketones and esters has been established without the use of any metal catalysts. Three types of nitriles (CH3CN, CH3CH2CN, and CH3CH2CH2CN) were employed as nucleophilic nitrogen sources. A new mechanism has also been proposed to explain the resulting regio- and stereoselectivity.
