Formation of allenyl ketones, 3-ethynylcoumarins, and arylfurans, furylfurans, and furylthiophenes by flash vacuum thermolysis of 3-methylidenefuran-2(3 H)-ones

Koch, Rainer,Berstermann, Hans Michael,Wentrup, Curt

, p. 65 - 71 (2014/01/17)

Flash vacuum thermolysis (FVT) of 3-methylidenefuran-2(3H)-ones 3 causes cheletropic extrusion of CO with formation of allenyl ketones 4. o-Chloro- and o-bromophenylmethylidenefuranones also afford allenyl ketones upon flash vacuum thermolysis, but in add
