Formation of cyclopropanes by the reductive coupling of 1,3-dihalides promoted by titanocene(II) species
The treatment of various 1,3-dihalides including the ones bearing an ester group with the titanocene(II) species produced cyclopropanes in good yields. The reaction of dihalides possessing two secondary halogens proceeded stereoselectively to afford traps-isomers as major products.
