Abstract

Abstract : The reaction of Ph2 P(O)H with B(C6 F5 )3 provided the Lewis pair complex Ph2 (H)POB(C6 F5 )3 (5 ) containing a bipolar + P–O–B – linkage. The reaction of5 with [(tht)AuCl] (tht = tetrahydrothiophene) proceeded with elimination of HCl and formation of [{(C6 F5 )3 BOPPh2 }Au(tht)] (6 ), which can be regarded as push–pull complex between a zwitterionic OPPh2 Au unit and a hard Lewis acid, B(C6 F5 )3, coordinating at the oxygen atom, and a soft Lewis base, tht, coordinating at the gold atom. Abstract : [{(C6 F5 )3 BOPPh2 }Au(tht)] contains a push–pull complex between a zwitterionic OPPh2 Au unit and a hard Lewis acid, B(C6 F5 )3, coordinating at the oxygen atom, and a soft Lewis base, tht, coordinating at the gold atom (tht = tetrahydrothiophene).
