Abstract

Three novel aminophosphine ligands (containing direct P-N bond), tert-butyl-NH(Ph2P), 2-picolyl-NH(Ph2P) and 2-picolyl-N(Ph2P)2, have been synthesized via aminolysis reaction of PPh2Cl and tert-butyl amine and 2-picolyl amine(in case of mono derivative reaction carried out in 1:1 and in case of di derivative in 2:1 ration) respectively. Oxidation of the aminophosphines with elemental selenium gave the corresponding selenides 2-picolyl -NH(Ph2P=Se) and 2-picolyl-N(Ph2P=Se)2. The borane derivatives were synthesized by reaction of the aminophosphines and BH3.SMe2. The bromides of tert-butyl-NH(Ph2P) were prepared by the oxidation of it by bromine. The new compounds were characterised by NMR, IR spectroscopy. Furthermore, representative solid-state structures of the compounds were determined using single crystal X-ray diffraction analysis.
