Redn. of benzodithiolethiones I (R = R1 = R2 = H; X = X1 = X2 = S) by DIBAL or BH3ŚMe2S in refluxing PhMe gave 88-94% benzodithiole I (X2 = H2). Similarly I (R = R1 = R2 = H; X = X1 = S; X2 = Se) gave 92% I (X2 = H2) and I (R, R1, R2 = H, OMe, NO2, NH2, OAc etc.; X = X1 = X2 = S) gave I (X2 = H2) in 63-96% yields whereas the O analogs, e.g. I (R = R1 = R2 = H; X = X1 = O; X2 = S, O) underwent ring cleavage to give benzenedithiol and I (R = R1 = R2 = H, X = X1 = X, X2 = O) gave 58% I (X2 = H2) and 21% II.
