The facile insertion of elemental sulphur into the cumulated linear triple bond , of (cp=η-C5H5) resulted in the isolation of , , and , with relative yields dependent on the reaction conditions, as well as the sulphur selenides S7Se and S6Se2.Detailed n.m.r. and t.l.c. studies indicated that the transformation occured via dichalcogen species of the type and .It was demonstrated that also can undergo a rapid reaction with elemental sulphur to give as the ultimate product.
