Resumen de An Aldehyde Derivative
J. Hodge Markgraf, Bo Yoon Choi
In connection with qualitative analysis schemes for organic laboratory experiments, a safe and convenient procedure is described for the small-scale preparation of an aldehyde derivative. Aliphatic and aromatic aldehydes are converted to 3-substituted-1,5-dihydro-2,4-benzodithiepines in high yield when treated with 1,2-benzenedimethanethiol in dichloromethane at room temperature with catalysis by ferric chloride on silica gel. The products are readily recrystallized from ethanol. Melting points for 27 derivatives are tabulated.
