η5-cyclopentadienyl, acetylacetonato, aceto-, benzamidino-, and allyl complexes, which retain the orthometallated amidino-group. Treatment of the chloride-bridged platinum complexes with CO under pressure causes carbonylation to form [PtR′NC(R)C6H3R″}(CO)Cl], whereas for palladium cleavage of the orthometallated ligand from the metal occurs with formation of the corresponding quinazolin-4-one. The six-membered nature
在甲醇水溶液中,K 2 [MCl 4 ](M = Pd或Pt)与具有芳基取代基的甲form,乙am和苯am [R'NHC(R)NR']反应形成微溶的正金属配合物。N,N'-二芳基甲am和-乙am形成六元金属环[M [R'NC(R)NH-C 6 H 3 R''] Cl} n ],而对于N,N'-二芳基苯甲having具有同时产生了N-和C-芳基取代基五元金属环[M [R'NC(C 6 H 4)NHR'] Cl} n ]。相关配合物由Np的反应形成-K 2 [PdCl 4 ]-对甲苯乙酰胺和对乙酰苯胺。在溶液中加热时的加合物[M R'NC(R)-NHR'} Cl 2 ]也产生原金属化的配合物。低聚的氯化物桥/聚合物材料被切割以得到吡啶和二甲亚砜的加合物,而氯配体引线的位移到η 5 -环戊二烯基,乙酰丙酮,aceto-,benzamidino-和烯丙基络合物,其保留orthometalla
