Abstract

Изучены реакции нового пинцерного комплекса бис((дифенил)фосфинокси)фенил платины [C 6H3–1,3-(OPPh2)2]Pt-С≡С-(4-C 6H3N 2S) (1), содержащего (2,1,3-бензотиадиазол-4- ил)-алкинильный лиганд, с соединениями Pd(CH3CN)2X2 (X = Cl, Br), Pt(dmso)2Cl2, Pd2(dba)3 и CuCl. Установлено, что при взаимодействии 1 с галогенсодержащими комплексами происходит трансметаллирование – перенос алкинильного лиганда с атома платины пинцерного комплекса на атом металла вводимого реагента. При этом реакция 1 с хлоридом меди (I) протекает обратимо. Полученные комплексы охарактеризованы методами ИК- и ЯМР-спектроскопии

The reactions of the new pincer complex bis((diphenyl)phosphinoxy)phenyl platinum [C 6H3– 1,3-(OPPh2)2]Pt-С≡С-(4-C 6H3N 2S) (1) containing (2,1,3-benzothiadiazole-4-yl)-alkynyl ligand with transition metal substrates Pd(CH3CN)2X2 (X = Cl, Br), Pt(dmso)2Cl2, Pd2(dba)3 and CuCl were studied. The interactions of 1 with halogen–containing complexes were found to proceed through transmetalation – the transfer of the alkynyl ligand from the platinum atom of the pincer complex to the metal atom of the second reagent. The reaction of 1 with copper (I) chloride is reversible. The complexes obtained were characterized by IR- and NMR-spectroscopy
