Abstract Organomercurials of 2-mercapto-5-methyl-1,3,4-thiadiazole and 2-mercapto-5-[4′-methyl quinolinyl-2-oxy methyl] -1,3,4-oxadiazole with aryl mercuric chloride have been synthesized under microwave irradiation in open vessels in a domestic microwave oven within a few minutes. This reaction rate was ca 100 times faster than the reaction rate in the conventional way. These organomercurials have a

Second-order rate constants are reported for the reaction of some YC6H4SnEt3 compounds with mercurichalides in tetrahydrofuran, and show that the reaction is one of low selectivity. The substituent effects can be correlated only in terms of Hammett σ-constants, and the data for the meta-methoxy group are anomalous. The results indicate that the rate determining step involves reaction of a π-complex
报道了一些YC 6 H 4 SnEt 3化合物与卤化汞在四氢呋喃中反应的二级速率常数,表明该反应是低选择性的反应之一。仅就哈米特σ常数而言,取代基效应可以相关,并且间甲氧基的数据是反常的。结果表明,速率确定步骤涉及π-络合物的反应。报告激活参数,并与建议的机制一致。

Aim: To synthesize and characterize organomercurycomplexes. Background: Organomercurycomplexes have reported for different antimicrobial activities. Objectives: Synthesis of organomercurycomplexes with piperidine thiohydrazide ligand and characterization, applications. Methods: Complexes were synthesized by modified reported methods. Spectral (IR, UV, 1HNMR) and TG/DTA analyses were used to characterize
