This paper describes the regioselectivediamination of conjugated dienes using inexpensive Cu(I) as catalyst and N,N-di-tert-butylthiadiaziridine 1,1-dioxide as nitrogen source. The regioselectivity of diamination is likely due to dual mechanistic pathways which are greatly influenced by reaction conditions and the nature of the diene. A variety of useful internal and terminal cyclic sulfamides can
