Zheng, Jian published the artcile1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU)-Promoted Decomposition of Difluorocarbene and the Subsequent Trifluoromethylation, Name: 2-Iodobenzofuran, the publication is Organic Letters (2015), 17(3), 532-535, database is CAplus and MEDLINE.
Difluorocarbene derived from various carbene precursors could be effectively decomposed by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). This decomposition process was successfully applied in the subsequent trifluoromethylation of a variety of (hetero)aryl iodides without the addition of an external fluoride ion. Mechanistic investigation revealed the detailed difluorocarbene conversion process in which the decomposed difluorocarbene is finally transformed into a fluoride ion and carbon monoxide.
Organic Letters published new progress about 69626-75-1. 69626-75-1 belongs to benzofurans, auxiliary class Iodide,Benzofuran, name is 2-Iodobenzofuran, and the molecular formula is C9H17NO, Name: 2-Iodobenzofuran.
