In chemistry a carbenoid is a reactive intermediate that shares reaction characteristics with a carbene. In the Simmons–Smith reaction the carbenoid intermediate is a zinc / iodine complex that takes the form of I-CH2-Zn-I This complex reacts with an alkene to form a cyclopropane just as a carbene would do.
