Synthesis of fluorinated malonamides and use in L/L extraction of f-elements

Synthesis of new fluorinated tertiary malonamides (F-malonamides) was accomplished, and their liquid/liquid (L/L) extraction properties with f-elements were investigated. These molecules are fluorinated analogues of well known extractants used in several processes designed towards the treatment of nuclear wastes, and the efficient separation of lanthanides from minor actinides; however, the synthesis of F-malonamides deserved a modification of the general synthetic route commonly employed to prepare H-malonamides. Extraction of neodymium from various aqueous media into both fluorous and classical solvents was studied, which revealed an opposite trend between F-malonamides and H-malonamides: L/L extraction ability is very sensitive to the nitrogen atoms substitution pattern, and the most efficient F-malonamide is compound 3 (R1 = Me), whereas the best H-malonamide is compound 5 (R1 = Bu, DMDBTDMA).

(2-Pyridyl)iminopropadienone

(2-Pyridyl)iminopropadienone 13 is generated by flash vacuum thermolysis (FVT) of 2-substituted pyrido[1,2-a]pyrimidin-4-ones 9 and observed by IR spectroscopy. Addition of HCl to 13 causes reversion to the starting material 9b, whereas addition of nucleophiles leads to malonic acid imide derivatives (23, 24, 26, 27, 28). The latter undergo thermal elimination of amines to regenerate 2-substituted pyridopyrimidinones. A competing retro-ene reaction occurs on FVT of 2-(dialkylamino)pyridopyrimidinones 9c,d, presumably in the oxoketenimine intermediates 22/25, with formation of the unsubstituted pyridopyrimidinone 31.

A simple general method for conversion of functionalized esters to functionalized amides

An efficient and easy new method for the conversion of amino-esters into amino-amides is described. In a one pot reaction between dialkyllithium amide and some amino-esters of thiophene and benzene, the corresponding amino-N-dialkylamides have been synthesized in high yields. The method was extended to malonic and phenylacetic esters. The reaction mechanism involves an anionic intermediate characterized by germylation.
