Lohner, W.,Praefcke, K
, p. 173 - 178 (1980)
The syntheses and chemical behaviour of ortho-butylseleno-and ortho-butyl-telluro-substituted ω-diazoacetophenones are described for the first time.Seleno- and telluro-3-coumaranone are obtained by novel routes involving cyclization of these diazoketones.
