Single bonding, metal-amide

The P-N bond in phosphinous amides is essentially a single bond, so the lone pairs on N and P are available for electrophiUc reagents and for donor bonding towards metal atoms. Proton addition to the N atom of HjPNHj has been calculated to loosen the P-N bond, whereas protonation at P renders this bond stronger than in the parent molecule [26]. NH-Phosphinous amides are practically not associated by intermolecular hydrogen bonds [27]. [Pg.80]

Oxazoline functionalization of a singly bonded C o dimer was achieved via a one-pot reaction of CgoECBn with OH and aromatic nitriles (14JOC197). A simple metal-free heterocyclization of uracil amides 158 was efficiendy carried out with hypervalent iodine Phl(OAc)2 in the presence of BF3 OEt2 affording pyrimidine-annulated oxazolines 159 in high yields (14TL5625). [Pg.340]
