Article abstract of DOI:10.1021/ja00179a004

The first X-ray crystal structure of a lithium azaenolate derived from a carboxylic acid amide is presented. A hexameric aggregate of lithium N-isopropylbenzamide crystallizes from a THF/TMEDA/hexane mixture at room temperature. Six lithiums and six oxyge
