WebThe present invention relates to a process and a system for the production of hydrogen and carbon dioxide starting from a feed stream comprising carbon monoxide, which is reacted with water and a halogen reactant. The process in particular comprises the steps of: a) reacting in a first reaction zone a feed stream comprising carbon monoxide (CO) with … WebThe chemistry of phosphiranes commenced in 1963 when the first derivatives, including the parent phosphirane, were described in two patents. [7,8] Important aspects of the rapidly developing synthesis of phosphiranes and, in particular, their diverse reactivity, have been reviewed. [9,10]

The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (often called a Wittig reagent) to give an alkene and triphenylphosphine oxide. The Wittig reaction was discovered in 1954 by Georg Wittig, for which he was awarded the Nobel Prize in Chemistry in 1979. WebIn this investigation we found also that the radical obtained by photolysis of bis(2,2'-biphenylene)phosphorane at -120° appeared to be identical with the radical obtained by electrochemical reduction of the bis(2,2'-biphenylene)phosphonium ion. Irradiation of the phosphorane which has a trigonal bipyramidal (TBP) configuration results in a ... put sredine
