Information × Registration Number 0204U000677, 0101U000687 , R & D reports Title C-Phosphorylated pyrroles and pyrazoles in synthesis of novel fused phosphorus-containing heterocycles. popup.stage_title Head Pinchuk A.M., Registration Date 18-02-2004 Organization Institute of Organic Chemistry National Academy of Sciences of the Ukraine popup.description2 It was established that phosphorylation of electron-rich five-membered heterocycles connected with one- or two atoms linkage afforded dipyrrolophosphinines and pyrazolopyrrolophosphepines - new types of condensed tricyclic systems embedding six- and seven-memebered central phosphorus-containing heterocycles, respectively. New heterocyclisation of 5-pyrazolylamides with phosphorus trichloride giving new type of condensed phosphorus-containing heterocyclic systems incorporating previously unknown moiety of 1,5,2-oxoazaphosphinine was found.
