In chemistry, phosphine-boranes are organophosphorus compounds with the formula R3−nHnPBH3. They are Lewis acid-Lewis base adducts derived from organophosphines (PR3−nHn) and borane (BH3). They are generally colorless or white solids. Since these adducts are air-stable, they represent a protected form of the parent organophosphine. iowa state men\u0027s basketball ncaa scheduleWebThe present invention relates to a process for preparing isocyanate homopolymers containing uretdione groups, in which the phosphinoboron compound of formula (I) are used as catalysts to catalyze the homopolymerization reaction of raw isocyanates, thereby obtaining a solution of isocyanate homopolymers having uretdione groups, then … open growth plates vs closed growth platesWebSynthesis and Structures of New 1,3,2,4‐Diphosphadiboretanes Semantic Scholar.
