Phosphorus based additives for flame retardant polyester. 1. Low molecular weight additives

Abstract

r value (r^= 0.01) itself shows microblock structure of the copolymer. This is also reflected in the composition dependence of the clearing temperatures. AcknowledgmentWe are indepted to Mr. A. Csehi (Gedeon Richter Factory) for the NMR measurements and to Dr. A. Dankovics (our Institute) for the IR measurements and calculations.

Transition-Metal-Catalyzed Addition of Heteroatom−Hydrogen Bonds to Alkynes

“…Alkenylphosphine oxides also possess a wide spectrum of applications either as biologically active compounds, fire retardants, or ligands for homogeneous catalysis 438 and asymmetric synthesis .…”

Rhodium-Catalyzed Regio- and Stereoselective Addition of Diphenylphosphine Oxide to Alkynes

“…Carbon−carbon bond formation is also achieved via reactions with carbanion species 5 or carbon-centered radicals . Thus, a wide spectrum of practical applications have been found in the derivatives of alkenylphosphine oxides, including biologically active compounds, fire-retardants, and ligands for homogeneous catalysts. 3d,4b Despite these diverse applications, methods for their preparation are limited . The recently revealed metal-catalyzed addition of P(V)−H bonds to alkynes provided a new clean methodology for the generation of alkenylphosphorus compounds .…”

Oxidative Addition of HP(O)Ph2 to Platinum(0) and Palladium(0) Complexes and Palladium-Catalyzed Regio- and Stereoselective Hydrophosphinylation of Alkynes

“…Carbon−carbon bond formation is also easily achieved by the reactions with carbanion species or carbon-centered radicals fire retardants, ligands for homogeneous catalysts, 3d,4b etc. Despite these diverse practical applications, however, synthetic methods available are quite limited .…”
