An Efficient Synthesis of Vinylphosphonates from Alkyl Cyanoformates, Activated Acetylenes, and Trialkyl Phosphites
An efficient synthesis of vinylphosphonates is described. This involves the reaction of alkyl cyanoformates and dialkyl acetylendicarboxylates in the presence of trialkyl phosphites. The 1H, 13C NMR, and 31P NMR spectra of vinylphosphonates having different substitution are consistent with the presence of two geometrical isomers.

been studied for R=Me, Et, i-Pr, and Ph. The reactions are studied by 15N and 31p NMR spectroscopy. Two 31p NMR resonances were observed for R3PAuCN and (R3P)2Au+ species. However, for the 15N NMR, only averaged resonances were observed for R3PAuC15N and Au(C15N)2" species except for Et3PAuC15N, where two resonances were detected.The R3PAu13C15N complexes have also been prepared where R= Me, Et...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
PREPARATION AND CHARACTERIZATION OF Mn (III) COMPLEXES
We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted
