Silica-anchored organotin trichloride: a recyclable and clean organotin catalyst for transesterification reactions.
A new synthetic scheme towards silica-supported organotrichlorotin derivatives has been developed. It involves the synthesis of (11-triethoxysilyl)undecyltricyclohexyltin, followed by sol-gel processing and, subsequently in the formation of the resulting hybrid silica, by electrophilic substitution of the tricyclohexyltin function by the target grafted trichlorotin using tin tetrachloride. HR-M...
متن کاملSynthesis and Antifungal Activity of Some Organotin(IV) Carboxylates
Six diorganotin(IV) carboxylates prepared by reacting diorganotin(IV) dichlorides with the respective silver carboxylate have been tested for antifungal activity against Aspergillus. niger, Aspergilluus flavus and Pencillium. citrinum in Sabourand dextrose broth. The compounds generally exhibit greater fungitoxicity than the diorganotin(IV) dichlorides and the carboxylic acids from which they w...
متن کاملSynthesis and Spectroscopic Characterization of Some New Coordination Compounds of Organotin (IV) with Carbohydrazones
Some new coordination compounds of tin(IV) having general formula [SnBu2 (L)2 ] (where L = carbohydrazone ligand) have been synthesized by the reaction of dibutyltin oxide with carbohydrazone ligands with the ratio of 1:2 (metal- ligand) using dry benzene as a reaction medium. The newly synthesized complexes were characterized by elemental analysis, molecular weight determinations, conductivity...
متن کاملThe synthesis of some organotin (IV) compounds in the melt- phase
The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...
متن کاملSOME UNUSUAL REACTIONS OF 3-PHENYLAMINOISOXAZOL-5 (2H)- ONES
3-Phenylaminoisoxazol-5(2H)-ones,s ubstituted on nitrogen with an isoquinoline or quinazoline group, react with tertiary amine bases to give imidazo annelated compounds. When the N-substituent is a nitropyridine, 2-aminoindole derivatives are formed instead. Evidence is presented that the reactions proceed by initial addition of the tertiary arnine to C-4
