ABSTRACT:
Organothio-tin compounds of the general formula ##EQU1## in which R represents a p-xylylene radical or a ##EQU2## radical, useful as catalysts in the polycondensation of organosilicon compounds, are prepared by reacting a di-octyl tin oxide with the diester obtained by reacting thioglycollic acid with 2,2'-dihydroxy-dipropyl ether or p-xylylene glycol.
