✦ Synopsis

Bis(amido)cyclodiphosphazanes, cis- [(tBuN-µ)

(2) and cis- [(tBuN-µ) 2 (PNC 4 H 8 NMe) 2 ] (3) were synthesized by treating the corresponding amines with cis-[ClP(tBuN-µ) 2 -PCl] (1). The stoichiometric reactions of 2 or 3 with elemental sulfur and selenium afforded the bis-chalcogenides, cis-[(tBuN-µ) 2 (P(E)NC 4 H 8 X) 2 ] (X = O, E = S; 4, X = NMe, E = S; 5, X = O, E = Se; 6, X = O, E = Se; 7). The reactions of 2 or 3 with [PdCl 2 (SMe 2 ) 2 ] produced exclusively the mononuclear trans-[PdCl 2 {(tBuN-µ) 2 (PNC 4 H 8 X) 2 } 2 ] (X = O; 8, X = NMe; 9), whereas the reactions with [Pd(µ-Cl)(η 3 -C 3 H 5 )] 2 afforded the bimetallic complexes [{PdCl(η 3 -C 3 H 5 )} 2 {(tBuN-µ) 2 (PNC 4 -H 8 X) 2 }] (X = O; 10, X = NMe; 11) in good yield.
