The behaviour of Lawesson's reagent and dialkylaminophosphines towards dicyanomethylene derivatives of xanthone and fluorenone

Article abstract of DOI:10.1515/HC.2003.9.5.457

Lawesson's reagent 1 reacts with xanthen-9-ylidenemalono-nitrile 3 to give adducts 5a, 6a and 7, respectively. In case of the reaction of fluoren-9-ylidenemalononitrile 4 with 1, only 3-amino-2-fluoren-9-ylidene-3- thioxopropanenitrile 5b is obtained toge
