Dimeric benzothiophene-based palladacycles were synthesized from thioanisole-substituted perfluoroalkyl propargyl imines and palladium(II) salts via an intramolecular thiopalladation pathway. The treatment of benzothiophene-based palladacycles with an excess of phosphine ligands in benzene at room temperature selectively afforded trans-bis(phosphine) palladium complexes in good yields. The tran...
Cyclometallated compounds obtained via the well-known intramolecular C-H activation by transition metals of Nor Scontaining ligands may lead to organic heterocycles through reaction with alkynes. The mechanistic implications of the formation of both C-C and C-Y bonds are discussed. A reaction pathway involving insertion of the alkyne into the metalcarbon bond of the starting material followed b...
بتا-سیکلودکسترین ، قادر به تشکیل کمپلکس محاطی inclusion complex)) با شمار زیادی از مولکولها از جمله داروهای کم محلول و ناپایدار و ... است که در نتیجه تشکیل این کمپلکس ، حلالیت و پایداری این داروها افزایش می یابد.
چکیده در این پایان نامه، در ابتدا از واکنش بین پالادیم استات و آلیزارین زرد gg کمپلکس دو هسته ای ارتوپالادیت [pd{? 2(c,n) -{5-(3-nitrophenylazo) salicylic acid}}(µ-oac)]2 (1) ستنز شد. از واکنش این کمپلکس دو هسته ای ارتوپالادیت (1) با لیگاند های تک دندانه تری فنیل فسفین (pph3)، 6،4،2-تری متیل-پیریدین(me3py) کمپلکس های تک هسته ای (2)، (3) سنتز شدند. همچنین از واکنش بین پالادیم استات و آلیزارین ز...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
The proper determination of Pd(II) ions in the presence Pt(IV) a waste solution is an intricate analytical issue. Having knowledge about composition, we are able to properly design processes and their selective separation recovery. Other important aspect related dyes removal coming from textile industry, which still not resolved. To solve these issues, this work, propose twin solution, describe...
Palladium(II) complexes are an important class of cyclopalladated compounds that play a pivotal role in various pharmaceutical applications. Here, we investigated the antitumour, anti-inflammatory, and mutagenic effects of two complexes: [Pd(dmba)(Cl)tu] (1) and [Pd(dmba)(N3)tu] (2) (dmba = N,N-dimethylbenzylamine and tu = thiourea), on Ehrlich ascites tumour (EAT) cells and peritoneal exudate ...
As reações do ciclopaladado catiônico [Pd(N,C-dmba)(MeCN) 2 ](NO 3 ) (1) (dmba = N,Ndimetilbenzilamina), como os pré-ligantes 3,5-dimetilpirazol (Hdmpz); 2-quinolinatiol (qnSH) e 1,1’-bis(difenilfosfina)ferroceno (dppf) levaram à formação dos compostos, respectivamente, [Pd(N,C-dmba)(Hdmpz)(ONO 2 )]0.5CH 2 Cl 2 (2), [Pd(N,C-dmba)(qnSH)(ONO 2 )] 0.5CH 2 Cl 2 (3) e [Pd(N,C-dmba)(dppf)](NO 3 ) (4)...
