Abstract: Various implementations relate to a system that provides a collection of deals to a mobile application on a client device. The mobile application then filters the deals based on relevance using a user profile within the client device, and displays the deals to a user. The display of the deals may be governed by the relevance of the respective deals as determined by matching of the deals with the user profile within the client device.

Abstract: Aromatic compounds such as toluene and o-xylene are chlorinated in the presence of a catalyst combination prepared by combining (A) at least one salt comprising a metal selected from the group consisting of a Group 4-12 metal, a lanthanide and an actinide; and a counterion; and (B) at least one organic sulfur compound, preferably phenothiazine-N-carbonyl chloride. The catalyst combination may include reaction products of (A) and (B). Under these conditions, production of the p-chloro isomer is optimized. In some embodiments said counterion is an organic counterion derived from at least one acidic organic compound selected from the group consisting of those with an approximate pKa value relative to water of at least about 3.

Abstract: A method for ring-halogenating an aromatic compound comprises contacting the aromatic compound with chlorine or bromine in the presence of a catalyst composition, where the catalyst composition comprises at least one salt comprising a metal selected from the group consisting of Group 13 metal; and a counterion derived from an acid having a pKa relative to water of 0 or greater; and at least one organic sulfur compound.
