readily gave the tellurides (SB)ArTe (Ar = Np (1A), Mes, (1B)) but that of dichlorides derived from methylketones was complicated due to partial decomposition to tellurium powder and diarylditelluride (Ar2Te2), resulting in poor yields of the corresponding tellurides 2A, 2B and 3A. Oxidation of the isolated tellurides with SO2Cl2, Br2 and I2 yielded the corresponding dihalides. All the synthesized compounds
描述了不对称的二有机碲化合物的合成和表征,该化合物包含空间上需要的1-萘或间苯三甲配体以及能够进行1,4-Te⋯N(O)分子内相互作用的小分子螯合有机配体。ArTeCl 3(Ar = 1-C 10 H 7,Np; 2,4,6-Me 3 C 6 H 2,Mes)与(SB)HgCl的反应[SB = Schiff碱2-(4,4 '-NO 2 C 6 H 4 CHNC 6 H 3 -Me)]或甲基酮(RCOCH 3)得到相应的二氯化物(SB)ArTeCl 2(Ar = Np,1Aa ; Mes,1Ba)或(RCOCH 2)ArTeCl 2(Ar = Np; R = Ph(2Aa),Me(3Aa),Np(4Aa); Ar = Mes,R = Ph(2Ba))。Na 2 S 2 O 5还原1Aa和1Ba可以容易地得到碲化物(SB)ArTe(Ar = Np(1A),Mes,(1B)),但是由于部分分解为
