A novel receptor based on the 4,5-diamine-9,9-dimethylxanthene skeleton functionalised with triflamides has been developed and its hydrogen-bonding donor ability is examined and compared with that of thiourea groups. The novel receptor also shows its

α-oxodithioesters react rapidly with diazomethane at -80° yielding thiadiazolines, which after N 2 extrusion form thiocarbonyl ylides. These ylides undergo electrocyclic ring closure. However, in the presence of strong dipolarophiles they can be tr
