Abstract: The invention comprises compounds of the general formula in which the residues attached to the Ti atoms are -OR or -O-Sn(R11) 2 - and the residues attached to the Sn atoms are or -OOC.R1 where R, R1 and R11 are defined below. R1 is alkyl or alkenyl having 1-18 C atoms, phenyl or phenyl substituted by up to 5 alkyl radicals having up to 6 C atoms each or 2 R1together may form a divalent aliphatic hydrocarbon radical having up to 3 double bonds R11 is alkyl of 1-18 C atoms, phenyl, alkyl phenyl of 7-12 C atoms, or phenyl-alkyl of 7-12 C atoms R is alkyl of 1-6 C atoms, aminoalkyl of 1-6 C atoms. benzyl, phenyl or 2 radicals R may be joined to form an alkylene radical of 2-12 C atoms. The compounds are made by reacting a diorganotin dicarboxylate e.g. (R1COO) 2 SnR 2 11with an orthotitanic ester e.g. Ti(OR) 4 . The reactants may be heated at 50-150 C. in an inert solvent e.g. a benzene hydrocarbon, an ether or a volatile petroleum fraction, preferably in a mole ratio of 2: 1 to 1: 2.The invention comprises compounds of the general formula <FORM:1054464/C2/1> in which the residues attached to the Ti atoms are -OR or -O-Sn(R11)2- and the residues attached to the Sn atoms are <FORM:1054464/C2/2> or -OOC.R1 where R, R1 and R11 are defined below. R1 is alkyl or alkenyl having 1-18 C atoms, phenyl or phenyl substituted by up to 5 alkyl radicals having up to 6 C atoms each or 2 R1 together may form a divalent aliphatic hydrocarbon radical having up to 3 double bonds R11 is alkyl of 1-18 C atoms, phenyl, alkyl phenyl of 7-12 C atoms, or phenyl-alkyl of 7-12 C atoms R is alkyl of 1-6 C atoms, aminoalkyl of 1-6 C atoms, benzyl, phenyl or 2 radicals R may be joined to form an alkylene radical of 2-12 C atoms. The compounds are made by reacting a diorganotin dicarboxylate e.g. (R1COO)2SnR211 with an orthotitanic ester e.g. Ti(OR)4. The reactants may be heated at 50-150 DEG C. in an inert solvent e.g. a benzene hydrocarbon, an ether or a volatile petroleum fraction, preferably in a mole ratio of 2: 1 to 1: 2. ALSO: The invention comprises compounds suitable for use as catalysts in the vulcanization of organopolysiloxane compositions, the compounds having the general formula <FORM:1054464/C3/1> in which the residues attached to the Ti atoms are -OR or -O-Sn(R11)2, and the residues attached to the Sn atoms are <FORM:1054464/C3/2> or -OOC.R1 where R, R1 and R11 are defined below. R1 is alkyl or alkenyl having 1-18 C atoms, phenyl or alkyl-substituted phenyl, or 2R1 together constituting a divalent aliphatic hydrocarbon radical having up to 3 double bonds R11 is alkyl of 1-18 C atoms, phenyl, alkyl-phenyl of 7-12 C atoms, or phenyl-alkyl of 7-12 C atoms R is alkyl or aminoalkyl of 1-6 C atoms, phenyl, or 2R together as an alkylene radical of 2-12 C atoms. The compounds may be used as catalysts when vulcanizing a,o-dihydroxydiorganopolysiloxane with a cross-linking agent, e.g. an orthosilicate or polysilicate ester, an organo-trialkoxy silane such as methyl- or ethyl-triethoxy silane or an organotriacyloxy-silane such as methyltriacetoxysilane. The catalyst may be added as 0.1 to 10% by weight, either as such or as a solution in an inert organic solvent.
