The reaction of [Bu4N]2[Pd2Br6(Se2N2)] with [14]aneS4; an effective source of the diselenium dinitride unit

Reaction of [Bu(4)N](2)[Pd(2)Br(6)(Se(2)N(2))] with [14]aneS(4) results in eventual formation of Se(4)N(4); intermediates in this reaction include an air-sensitive insoluble material which reacts with [PtCl(2)(PMe(2)Ph)](2) to give the first example of a platinum adduct of Se(2)N(2) and with [Pd(2)Br(6)](2-) to regenerate the starting material.
