Cleavage of the PS bond of an R 2 PS function (R cyclohexyl), bound in a η 2 fashion to Mn(CO) 4 , through insertion of R 1 CP, followed by subsequent [2+2] cycloaddition of the product and a second molecule of R 1 CP, leads to the thiadiphosphole 1 . By decreasing the size of R stepwise (→ Ph → Me), the bicycle 2 and the pentacycle 3 can be formed. [Mn] Mn(CO) 3 , R1 t Bu.
