Patent number: 5164502Abstract: Chloro and bromophenols and N-acylanilines are fluorinated in an ortho or para position with an N-fluoropyridinium salt to obtain fluorohalophenols and N-acylfluorohaloanilines, which can be further converted to fluorophenols and N-acylfluoroanilines by reduction. Thus, o-fluorophenol is obtained by fluorination of p-bromophenol with 2-chloro-6-(trichloromethyl)pyridinium fluoroborate and reduction of the product obtained with sodium formate and a palladium catalyst. N-Fluoropyridinium salts having trichloromethyl substituents are disclosed.Type: GrantFiled: November 8, 1991Date of Patent: November 17, 1992Assignee: DowElancoInventors: Alexander P. Fung, M.

Patent number: 5155224Abstract: The process of this invention for preparing Mn(II) chelate comprises forming the Mn(II) chelate by mixing manganese (II) oxide (insoluble) with an aqueous suspension comprising a molar equivalent or molar excess of the insoluble protonated chelating compound at a temperature of from 20.degree.to 50.degree. C. When the reaction is carried out with a protonated chelating agent in the absence of base, a precipitate of the protonated Mn(II) chelate is formed. A low osmolarity MN(II) chelate solution can be formed from the precipitates by dissolving them in an aqueous solution of base. When the initial chelate forming reaction is carried out in a solution containing a molar equivalent or excess of sodium hydroxide, a low osmolarity solution of the Mn(II) chelate is directly formed with most chelating agents. Preferred chelating compounds for this process include DPDP, DTPA, DCTA, EDTP, DOTA, DOXA, DO3A and EDTA.Type: GrantFiled: June 23, 1989Date of Patent: October 13, 1992Assignee: Salutar, Inc.Inventors: Scott M.
