Gold (i) acid Esters mercaptocarboxilico procedure for its preparation and its application to Brown Solid Substrates.

摘要

Novel gold(I) mercaptocarboxylic acid esters of the formula (I) IMAGE in which X is a C1- to C3 alkylene group and Z is a group from the series tricyclo(5,2,1,02.6)decane-8- or -9-yl or tricyclo(5,2,1,02.6)decyl-3- or -4-methyl. These esters can be prepared from mercaptocarboxylic acid esters of the formula (II) IMAGE and from a gold(I) chloride-dialkylsulfide complex. The novel esters can be used in gold preparations for gilding solid bases, especially ceramic materials. Compared to known gold(I) mercaptocarboxylic acid esters, the novel esters result in considerably shorter drying times for gold preparations.
