Abstract

Three types of tetraazamacrocycles (1,4,8,11-tetraazacyclotetradecane, 1,4,8,12-tetraazacyclopentadecane, and 1,4,8,11-tetraazacyclotetradecane- 5,7-dione) are grafted on the surface of phosphorus-containing dendrimers possessing P(S)Cl2 end groups (for generations 1 and 3: this corresponds to three and twelve macrocycles, respectively) and on the model compound PhCH=NN(Me)P(S)Cl2. Depending on the nature of the macrocycle, the reaction induces the formation of five-membered rings (diazaphospholanes) or of six- membered rings (diazaphosphorinanes). The structure of the adducts is deduced from 13C NMR spectra and from X-ray diffraction studies of the reaction products (8, 9, 10) of the model compound.
