Addition of Azaenolates to Simple, Unactivated Olefins

Addition of Azaenolates to Simple, Unactivated Olefins

An olefinic analogue of the aldol reaction makes possible the ready synthesis of ketones by coupling the three components: zinc hdrazone, olefin (e. g. ethylene or styrene), and electrophile E+ (see below). Fine‐tuning the electronic properties of the carbometalated hydrazone is decisive for the suc...

Zusammenfassung:An olefinic analogue of the aldol reaction makes possible the ready synthesis of ketones by coupling the three components: zinc hdrazone, olefin (e. g. ethylene or styrene), and electrophile E+ (see below). Fine‐tuning the electronic properties of the carbometalated hydrazone is decisive for the success of this reaction.
