Researchers detail in 'Calixarene-monophosphines as supramolecular chelators,' new data in life sciences. According to a study from France, "The calix[4]arenes 5-diphenylphosphino-17-R1-11,23-diR2-25,26,27,28-tetrapropoxycalix[4]arene (1, R1=R2=Br; 2, R1=Br, R2=H; 3, R1=R2=p-tolyl; 4, R1=p-tolyl, R2=H; 5, R1=R2=H; 20, R1=p-tolyl, R2=H), all bearing a diphenylphosphino group attached to the calixarene upper rim, have been synthesised starting from 5,11,17,23-tetrabromo-25,26,27,28-tetrapropoxycalix[4]arene. Reaction of 1-5 with [RuCl2(p-cymene)]2 leads quantitatively to monophosphine complexes, [RuCl2(p-cymene)L], in which the endo-oriented ruthenium atom unit sits inside ...
