Phosphorus-containing compounds complexes with

Reaction of (l-alkynyl)carbene complexes with nitrogen- or phosphorus-containing compounds makes available a large variety of products. Among these are (enamino)carbene and ( enphosphino )carbene complexes, both of which have been widely used for the generation of organic products. 

Phospholipids are phosphorus-containing compounds based on fatty acids esterified with glycerol or a nitrogenous base. They are important as constituents of the lipoprotein complexes of biological membranes. 

Surprisingly, very few publications reporting the use of bismuth catalysts have appeared in the field of polymer chemistry although bismuth(III) salts, due to their ability to form weak complexes with various heteroatoms and functional groups commonly encountered in polymer chemistry, clearly have potential as catalysts (Bronsted or Lewis cationic activation) for the synthesis of these special multi-Lewis base type of macromolecules. In one of the few reported examples, the polycondensation of dimethyl terephthalate with 1,4-butanediol has been carried out under BiCls catalysis and leads to telechelic poly(butylenes terephthalates) [125]. Bi(0Tf)3 xH20 has been patented as a catalyst for the cationic polymerization of THF using selected phosphorus-containing compounds [126].

A small amount of compound 71 with two oxygen atoms on the phosphorus atoms was obtained by oxidation of the azaphospholene 69 phosphorus atom and the complex 70 containing two BH3 groups by derivatization of 69 with the Lewis acid BH3-THF (Equation 29) <2001AGE3144>.
