New homopolymers and copolymers based on aromatic polyethers bearing side diphosphonate and diphosphonic groups have been synthesized. These synthetic efforts resulted in homo and copolymers of high thermal stability but moderate molecular weights. To eva

As a simple and efficient system, Cu(OAc)2 ? H2O and K2S2O8 can activate H-phosphonates to produce the corresponding dialkyl phosphoryl radicals. The obtained dialkyl phosphoryl radicals react smoothly with 2-amino-1,4-naphthoquinones, affording accurate preparation of various phosphoryl-functionalized 2-amino-1,4-naphthoquinones. The developed copper-catalyzed cross-dehydrogenative phosphorylation features broad substrate scope, easily available reagents, high atom economy and operational simplicity, which enables a practical avenue for C?P bond formation.

The reaction of P(O)-H compounds with p-quinones could proceed through either 1,4- or 1,6-addition pathways by employing different additives to selectively give the corresponding C- and O-phosphoryl hydroquinone derivatives in good yields. Oxidative doubl

Treatment of dialkyl aryl phosphates with n-butyllithium or lithium diisopropylamide results in a rearrangement that involves the fission of an oxygen-phosphorus bond and formation of a C-P bond yielding dialkyl (2-hydroxyaryl)phosphonates.A dialkyl (2-hy
