REACTIVITY OF GROUP-10 HALIDES TOWARD (PH2PN=)C(PH)[N(SIME3)(2)], (NC5H4)((PH2PN=)C[N(SIME3)(2)])-4 AND C6H4(C(=NPPH2)[N(SIME3)(2)])(2)-1,4

Interaction of [NiBr2(dme)] (dme = 1,2-dimethoxyethane) with 1 equival ent of (Ph2PN=)C(Ph)[N(SiMe3)(2)] L-1 in tetrahydrofuran gave cis-[NiB r2{(Ph2PNH)C(Ph)(=NH)}] 1, metathesis of this compound with excess NH4 BF4 in methanol gave cis-[Ni{(Ph2PNH)C(Ph)(=NH)}(2)][BF4](2) 2. Reacti on of [NiBr2(dme)] with 1 equivalent of (NC5H4){Ph2PN=)C[N(SiMe3)(2)]} -4 L-3 followed by metathesis with excess NH4BF4 in methanol gave cis- [Ni{(NC5H4)[(Ph2PNH)C(=NH)]-4}(2)][BF4](2) 3. Reaction of [PdCl2(PhCN) (2)] with 1 equivalent of L-1 in acetonitrile gave cis-[PdCl2{(Ph2PNH) C(Ph)(=NH)}] 4, and with 0.5 equivalent of C6H4{C(=NPPh2)[N(SiMe3)(2)] }(2)-1,4 L-2 in tetrahydrofuran gave -[(PdCl2)(2){C6H4[C(=NPPh2){N(SiM e3)(2)}](2)-1,4}] 5 and cis-[(PdCl2)(2){C6H4[C(NHPPh2)(=NH)](2)-1,4}] 6. Interaction of [PdCl2(PhCN)(2)] with L-3 in 1:1 and 3:2 molar ratio s gave cis-[PdCl2{(NC5H4)-[(Ph2PNH)C(=NH)]-4}] 7 and s-[PdCl2{cis-PdCl 2[(NC5H4){(Ph2PNH)C(=NH)}-4]}(2)] 8, respectively. Reaction of [MCl2(P hCN)(2)] (M = Pd or Pt) with 2 equivalents of L-3 followed by metathes is with excess NH4BF4 in methanol gave (Ph2PNH)C(=NH)]-4}{(NC5H4)[(Ph2 PNH)C(=N)]-4}][BF4] (Pd 9 or Pt 10). Crystal structures of compounds 1 , 4, 7, 8, 9 and 10 have been determined.
