Phenylbis phosphine

The heterocyclic acylphosphines (52) and (53) have been prepared by the reaction of phenylbis(trimethylsilyl)phosphine with the acid chlorides derived from phthalic and diphenic acids. The reaction of 2,3-dichloromaleic anhydride or thioanhydride with phenylbis(trimethylsilyl)phosphine gives derivatives of the 1,4-dihydro-p-diphosphorin system (54).45... [Pg.8]

There have been a number of new reports of reactions of this type including several involving addition to the aldehyde function of 161. Reaction with diphenyltrimethylsilylphosphine gave 162 while reaction with phenylbis (trimethylsilyl)phosphine gave 163 (Scheme 12) <2004TL6955>. [Pg.861]

Preparation.- Trialkyl or triaryl phosphites and trithiophosphites (55) can be obtained in 50-90% yields from white phosphorus, carbon tetrachloride, triethylamine, and the appropriate alcohol, phenol, or thiol in a polar aprotic solvent such as dimethylformamide. A series of racemic phenylbis(dialkylamino)phosphines (56) have been prepared in a one-pot synthesis as shown the bulk of the dicyclohexyl-amino group prevents substitution of the second chlorine atom, and the products (56) are claimed to be stable to air and moisture. In a one-pot synthesis tris(diethylamino)-phosphine has been treated successively with three different alcohols to give a 89% yield of the thiophosphate (57) after oxidation with sulphur. ...

The macrocyclic diphosphonite 25 was obtained in good yield from phenylbis-(diethylamino)phosphine. A new calix[4]arene tetrakis(dimethylphosphinite) (26) has been synthesised and its X-ray crystal structure determined. Both in... [Pg.86]

Phosphine and primary phosphines add to vinyl acetate to form (2-acetoxyethyl)-phosphines, e.g. (28), which can be hydrolysed to form (2-hydroxyethyl)phosphines, e.g. (29). The addition of phenylacetylene to phenylphosphine that is co-ordinated to a dicarbonylcyclopentadienylmanganese unit occurs stereospecifically, with the formation of (co-ordinated) phenylbis( ra 5 -/ -styryl)phosphine (30). ...
