摘要:
Process for the preparation of (cyclo)aliphatic uretdiones of improved color quality by reaction of (cyclo)aliphatic diisocyanates, if desired in an inert solvent, with the aid of from 0.5 to 3% by weight of a catalyst of formula (I) in the presence of from 0.1 to 4% by weight of a phosphorus compound of formula (II)
摘要:
This invention relates to the use of compounds having the general structure: wherein: Z1 and Z2 each independently represent an arene nucleus, which has from 5 to 14 ring atoms; G1 and G2 each independently represent a metal ligating group; R represents a hydrogen atom, a halogen atom, an alkyl group, an acylamino group, an alkoxy group, a sulfonamido group, an aryl group, a thiol group, an alkylthio group, an arylthio group, an alkylamino group, an arylamino group, an amino group, an alkoxycarbonyl group, an acyloxy group, a nitro group, a cyano group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfoxyl group, an arylsulfoxyl group, an aryloxyl group, a hydroxyl group, a thioamido group, a carbamoyl group, a suffamoyl group, a formyl group, an acyl group, a ureido group, an aryloxycarbonyl group, a silyl group, or a sulfoalkoxy group; L1 represents a nitrogen heterocycle; L2 represents a monodentate or polydentate (e.g., bidentate) ligand; X represents nitrogen or a methine (CH) group; M is a divalent or polyvalent transition metal ion where the coordination number is at least 4; and k, m, and n are whole numbers less than or equal to 3 as antimicrobial agents to inhibit the growth or replication of microorganisms such as viruses, bacteria, and fungi.
