Addition of Carbenes and Carbenoids to Olefins

Addition of Carbenes and Carbenoids to Olefins.— The addition of carbenes and carbenoids to olefins provides a standard method for the synthesis of cyclopropanes and much of the current work is concerned with the provision of new carbene sources and the improvement of procedures. 

The selectivity of addition of dihalogenocarbenes to steroidal and related model olefins has been examined.

Addition of Carbene and Carbenoids to Olefins.—The addition of carbenes and carbenoids to olefins continues to be one of the most popular routes used for cyclopropane synthesis. A review of carbenes (and nitrenes) based on the 1973 literature has appeared during the year, and methoxycarbonyl carbene has been the subject of a theoretical study. ...
