## Abstract The synthesis of calix[4]areneโbased phosphorus diamides and phosphites is described. These oligocyclic ligands have been tested in the Rh(I)โ catalyzed hydroformylation of 1โoctene. Depending on the reaction conditions, yields up to 99% and __n/iso__โselectivities between 0.7 and 2.6 h
A novel water soluble phosphine, N,N-dipolyoxyethylene-substituted-2-(diphenylphosphino)phenylamine (PEO-DPPPA), was synthesized by a two-step ethoxylation of 2-(diphenylphosphino)phenylamine (2-Ph 2 P-C 6 H 4 NH 2 , DPPPA). In the first step, DPPPA was ethoxylated without catalyst to give an interm
