Note on a Simple Synthesis of 2-Pyrrolin-4-ones The synthesis of 2-pyrrolin-4-ones by direct acid hydrolysis of 3-hydroxy-2-pyrrolecarboxylic esters is described.doi:10.1002/jlac.197619760218Georg PfeifferHelmut BauerWILEY‐VCH VerlagJustus Liebigs Annalen Der Chemie...
The closo-hydro-borate [B6H6]2- reacts with DBU in chloroform to give a mixture of two different seven-vertex monocarboranes, 3-DBU-closo-2-CB6H6 and [3-Cl-closo-2-CB6H6]-. Dichlorocarbene, which is generated in situ by the reaction of DBU with chloroform at elevated temperatures,...
The main result of the paper is that R has finite CM type if it dominates the local ring R ' of a simple plane curve singularity in the sense of Arnol'd (i.e. of type A k , D k or E 6 , E 7 , E 8 ). That R dominates R ' means just that R ' RR ' , where R '...
