Photolysis of 3-chloro-3-benzyldiaiirine in tetramethylethylene gives E-and Z-fi-chlorostyrenes and cyclopropans. Relative rate studies show that the styrenes to cyclopropane ratio increases with increasing diazirine concentration\_ This permits the determination of the ratio k,/ki= 8 where kD is th
