A novel radical domino process relying on the homolytic cleavage of P-S bonds allows the preparation of phosphorus-containing molecules through addition of P-centered radicals onto olefins. The key step of this reaction is a homolyticsubstitution on a sulfuratom. The scope of the reaction is broad. Diaminophosphonyl radicals whose reactivity was unknown react smoothly with olefins.

The first representative of the N-silylmethylamides of phosphoric acid O=P[NMe(CH2SiMen(OEt)(3-n)](3) have been synthesized by interaction of MeNHCH2SiMen(OEt)(3-n) (n-=2,3) with POCl3. The interaction of the N,N',N ''-trimethyl-N,N',N ''-tris[(ethoxydimethylsilyl)methyl]triamide phosphoric acid with BF3 center dot Et2O or BCl3 results in the formation of the N,N',N ''-trimethyl-N,N',N ''-tris[(fluorodimethyl-silyl)methyl]triamide phosphoric acid or N,N',N ''-trimethyl-N,N',N ''-tris[(chlorodimethylsilyl)methyl]triamide phosphoric acid. NMR data show on the tetracoordinate state of silicon in these products.
