The cage-like phosphine 1,3,5-triaza-7-phosphaadamantane (PTA) is attracting a lot of attention in coordination chemistry due to its favorable properties like stability to oxidation, small dimensions, solubility in water.

PTA molecule has a basic character, and it undergoes a selective nitrogen protonation, while the preferred coordination site is phosphorus.

Abstract
The cage-like phosphine 1,3,5-triaza-7-phosphaadamantane (PTA) is attracting a lot of attention in coordination chemistry due to its favorable properties like stability to oxidation, small dimensions, solubility in water. Actually, Ru, Pd, Pt, Au,Ag complexes containing PTA are under investigation for aqueous phase or biphasic homogeneous catalysis, anticancer activity, photoluminescence experiments as well as crystal engineering. PTA molecule has a basic character, and it undergoes a selective nitrogen protonation, while the preferred coordination site is phosphorus. However, unlike the related compound hexamethylenetetramine, PTA salts have been reported so far. We have therefore undertaken a systematic synthetic-structural study on PTA- nutraceutical acids salts, aimed at exploring the structural features of the interactions between the different molecules.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
