Carbene intennediates are produced by the photo lysis of diazomethane open parentheses C H subscript 2 end subscript N subscript 2 end subscript close parentheses or ketene open parentheses C H subscript 2 end subscript equals C equals 0 close parentheses. They are also produced by the reaction of C H X subscript 3 end subscript with base or by Simmons-Smith reaction. There are two types of carbenes, singlet and triplet. They are so called due to their spin state.
