The compounds are considered to be less likely to cause cardiovascular side effects and various other side effects associated with stimulation of beta-1 receptors, relative to epinephrine.Type: GrantFiled: April 19, 1993Date of Patent: May 24, 1994Assignee: Alcon Laboratories, Inc.Inventors: Billie M. York, Evan P. Kyba

Patent number: 5106407Abstract: The present invention discloses the antimicrobial utility of certain iodonium ylide compounds. The particular iodonium ylide compounds are phenyl iodonium ylides having an ortho substituent that stabilizes the positive charge on the polyvalent iodine by a nonbonded electrostatic interaction. The polyvalent iodine is further stabilized by a cyclic 1,3-dicarbonyl anion.Type: GrantFiled: December 4, 1989Date of Patent: April 21, 1992Assignee: The Dow Chemical CompanyInventors: Attila G. Relenyi, Gerald F. Koser, Richard W. Walter, Jr., William J. Kruper, Jr., Ravi B. Shankar, Anthony P. Zelinko

Patent number: 5068392Abstract: 2-Chloro and 2,6-dichloroanilines, optionally substituted in the 3-, 5-, and/or 6-position are prepared from the corresponding anilides by selective bromination, chlorination, reduction and hydrolysis. The selectivity of the process for introducing chlorines ortho to the amino group is very high.Type: GrantFiled: January 24, 1991Date of Patent: November 26, 1991Assignee: DowElancoInventors: Lennon H. McKendry, Mark W. Zettler

Patent number: 5026912Abstract: A process for selectively producing ortho-alkylated aromatic amines in high selectivity relative to N-alkylated aromatic amines. The process comprises reacting an aromatic amine, having at least one hydrogen atom in a position ortho to the amine functionality, and an olefin under conditions sufficient to effect an alkylation reaction, in the presence of a zeolite catalyst which has been thermally pretreated by heating the catalyst to a temperature greater than about 500.degree. C. for a period ranging from 0.5 to about 10 hours while sweeping an inert gas over the heated catalyst to remove water and ammonia formed during the thermal treatment, and subsequently recovering the alkylated aromatic amine.Type: GrantFiled: March 27, 1990Date of Patent: June 25, 1991Assignee: Air Products and Chemicals, Inc.Inventors: Rakesh Agrawal, Steven R.
