  • Patent number: 10099967
    Abstract: Disclosed are hypergolic salts with borane cluster anions that ignite spontaneously upon contact with nitric acid (from 70% to 100% in water) with short ignition delay. The salts, when added as trigger additive to combustible solvent or ionic liquids, make the resulting formulation hypergolic. The salts with borane cluster anions also shorten ignition delay in hypergols, such as RP-1, and additionally allow nitric acid to be used to replace liquid oxygen as an oxidizer. In some examples, the borane salts are formed in situ in an ionic liquid.

    Abstract: trans-RuH(&eegr;1-BH4)[(S)-xylbinap][(S,S)-dpen] (0.00125 mmol), acetophenone (5.0 mmol), and 2-propanol (2.5 mL) were placed in an autoclave, and the resulting solution was repeatedly subject 5 times to a procedure of performing pressure reduction and argon introduction while stirring the solution for deaeration. A hydrogen tank was then connected to the autoclave, and after replacing the air inside an introduction tube with hydrogen, the pressure inside the autoclave was adjusted to 5 atmospheres and then hydrogen was released until the pressure dropped to 1 atmosphere. After repeating this procedure 10 times, the hydrogen pressure was adjusted to 8 atmospheres and stirring at 25° C. was performed for 12 hours. By concentrating the solution obtained by depressurization and subjecting the crude product to simple distillation, (R)-1-phenylethanol (yield: 95%) in the form of a colorless oily substance was obtained at an ee of 99%.

  • Patent number: 6455718
    Abstract: Chloropentafluorobenzene or bromopentafluorobenzene is formed by heating perhalobenzene, C6FnX6-n where n is 0 to 4, and each X is, independently, a chlorine or bromine atom, with alkali metal fluoride, and an aminophosphonium catalyst (e.g., (Et2N)4PBr). The resultant chloropentafluorobenzene or bromopentafluorobenzene can be converted into a pentafluorophenyl Grignard reagent or a pentafluorophenyl alkali metal compound. This in turn can be converted into tris(pentafluorophenylborane), which can be converted into a single coordination complex comprising a labile tetra(pentafluorophenyl)boron anion (e.g., a trialkylammonium tetra(pentafluorophenyl)boron complex or an N,N-dimethylanilinium tetra(pentafluorophenyl)boron complex).
