| abstract | Lubricating compositions comprise bis (silylmetallocene) compounds of the formula [(R1)3Si-R-Y-Z-Y1]2A, where R is a divalent hydrocarbon or halohydrocarbon radical having at least 2 carbon atoms, A is R or methylene, R1 is a monovalent hydrocarbon, halohydrocarbon, cyanoalkyl, fluoralkyl or halogen radical, Y and Y1 are carbonyl, carbinol, carbamino, carbazido or methylene, Z is a divalent metallocene radical -[Q4C5]M[C5Q4]-, where M is a transition metal, Q is hydrogen, aryl, hydroxyaryl, cycloaliphatic, nitroaliphatic, aliphatic acyl, arylacyl, carboxyaryl, aldehydic, sulpho, carboxyaryl, nitroaryl, haloaryl or haloaliphatic.ALSO:The invention comprises bis-(silylmetallocene) compounds of the formula [(R1)3Si-R-Y-Z-Y1]2A where R is a divalent hydrocarbon or halohydrocarbon radical having at least 2 carbon atoms, A is R or methylene, R1 is a monovalent hydrocarbon, halohydrocarbon, cyanoalkyl, fluoralkyl or halogen radical, Y and Y1 are carbonyl, carbinol, carbamino, carbazido or methylene, Z is a divalent metallocene radical -[Q4C5]M[C5Q4]-where M is a transition metal, Q is hydrogen, aryl, hydroxyaryl, cycloaliphatic, nitroaliphatic, aliphatic acyl, arylacyl, carboxyaryl, aldehydic, sulpho, carboxyaryl, nitroaryl, haloaryl or haloaliphatic. Specified metals are titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zirconium, columbium, molybdenum, technitium, ruthenium, rhodium, palladium, hafnium, tantalum, tungsten, rhenium, osmium, indium and platinum. The compounds may be prepared by (1) reacting a dibasic acid anhydride XCOACOX, wherein X is halogen with two moles of the silylorganometallocene <FORM:1075542/C3/1> at - 25 DEG to 100 DEG C.; or (2) acylating a metallocene [Q5C5]M[C5Q5] with XCO.A.COX and acylating the product with two moles of a silylcarboxylic acid halide (R1)3Si-R1-COX; the carbonyl groups may be converted to other Y and Y1 groups by conventional methods. Suitable dibasic acid halides are o-, p- and m-phthaloylchloride, malonyl chloride, adipylchloride, succinylchloride, glutarylchloride, sebacoyl chloride; oxalylchloride yields bis-(silylmetallocene) compounds free of A radicals. Compounds containing a hydrolysable group may be hydrolysed to polysiloxane polymers and copolymers containing metallocene units. The examples describe the preparation of (1) 11,11 - bis(betatrimethylsilylpropionyl) terephthaloylferrocene; (2) 11,11 - bis(p - trimethyl-silylbenzoyl) adipylferrocene; (3) 11,11-bis-(gamma - trimethylsilylpropyl)p - xylylene-ferrocene; and (4) 11,11-bis(p-trimethylsilyl-benzoyl) terephthaloylferrocene. The compounds may be used as heat stabilizer for polysiloxanes-in (1) 11,11-bis(beta-trimethylsilyl-propionyl) terephthaloylferrocene is mixed with a polydimethylsiloxane gum, silica and benzoyl peroxide are added, and the composition cured. Other uses are U.V. absorbers, antioxidants, anti-knock materials, complexing agents, lubricants, coating materials and elastomers. |
