    Carbenes had first been postulated by Eduard Buchner in 1903 in cyclopropanation studies of ethyl diazoacetate with toluene. [29] In 1912 Hermann Staudinger [30] also converted alkenes to cyclopropanes with diazomethane and CH 2 as an intermediate. Doering in 1954 demonstrated their synthetic utility with dichlorocarbene.
