The synthesis of partially bridged thiophosphonate and phosphonate resorcinarenes is reported in this paper. Resorcinarenes functionalised at the upper rim with two or three P=X (X=S,O) bridges oriented towards the molecular cavity are obtained from the treatment of the corresponding (iiii) tetrasubstituted cavitand with 1,2-dihydroxybenzene and base in DMF. This synthetic route selectively promoted the formation of one of the two disubstituted resorcinarenes, the AC isomer. The crystal structure of the AC-dithiophosphonated resorcinarene 4 has been determined.

Abstract
The synthesis of partially bridged thiophosphonate and phosphonate resorcinarenes is reported in this paper. Resorcinarenes functionalised at the upper rim with two or three P=X (X=S,O) bridges oriented towards the molecular cavity are obtained from the treatment of the corresponding (iiii) tetrasubstituted cavitand with 1,2-dihydroxybenzene and base in DMF. This synthetic route selectively promoted the formation of one of the two disubstituted resorcinarenes, the AC isomer. The crystal structure of the AC-dithiophosphonated resorcinarene 4 has been determined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
