Preparation and NMR, Mass and Mössbauer Studies of Di-and Triorganotin (IV) Derivatives of 3-(2-Furanyl)-2- Propenoic Acid
3-(2-Furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula R3SnL (R=Me, Et, n-Bu, Ph and Cy) and R2SnL2 (R=Me and n-Bu). These complexes have been characterized by elemental analyses, IR, 1H-NMR, MASS and Mössbaure spectroscopy.
متن کاملPreparation and Characterization of Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 Complexes
We have recently synthesized Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 complexes. The reaction of TiCl3(THF)3 with NaBH4 in dry THF gave flat blue crystals, Ti(BH4)3(THF)3. The reaction of VCl3 with NaBH4 in presence of N, N, N', N'- tetramethyle...

متن کامل2 . 3 . 9 . Oxo - Anion Modified Oxides
In the interaction of two or more catalyst components, two extremes can be found: The formation of a compound or a solid solution constitutes the most intimate and homogeneous type of interaction, while the formation of a non-wetting surface species on an inert support can be seen as the minimal type of interaction. For supported catalysts, the goal is usually the dispersion of the active speci...
متن کاملPreparation of 2'-thio-2'-deoxycytidine 2':3'-phosphorothioate.
The synthesis of a novel ribonucleotide analog 2'-thio-2' deoxycytidine 2':3'-O,S-phosphorothioate is described. In the first step, 2,2'-anhydro 1-beta-D-arabinosylcytosine was thiophosphorylated by the action of dithiophosphate, a process which gave predominantly the 3'-O-phosphorothioate isomer. An intramolecular displacement reaction led to the formation of the title compound. Structure and ...
