Abstract
A method of producing phenyl silanes is provided by reacting a silane having at least one hydrogen-silicon bond and an aromatic compound having at least one halogen radical, aryl halide radical or aldehyde radical in the presence of a transition metal catalyst at a temperature in the range of about 150.degree. C. to 200.degree. C. Suitable transition metals include rhodium, ruthenium, palladium, osmium, iridium and platinum.
Claims15
A method which comprises effecting reaction between a silane having at least one hydrogen-silicon bond and a compound of from 6 to 30 carbon atoms having an aromatic nucleus and at least one monovalent radical selected from the class consisting of halogen and carbonyl groups of the formula ##STR17## wherein Y is selected from a group consisting of hydrogen and halogen, in the presence of a catalytic quantity of a transition metal at a temperature in the range of about 150.degree. C. to about 200.degree. C.
A method which comprises effecting reaction between a silane of the formula
- HSiR.sub.3
- and a compound selected from a group of substituted aromatic compounds having the formulas ##STR18## wherein R is a monovalent radical selected from the class consisting of hydrogen, halogen and organic radicals of from 1 to 30 carbon atoms, Ar is selected from a group consisting of polyvalent and monovalent aromatic radicals of from 6 to 30 carbon atoms, X is halogen and Y is selected from the group consisting of hydrogen and halogen in the presence of a catalytic quantity of a transition metal at a temperature in the range of about 150.degree. to about 200.degree. C.
A method of producing triethylphenylsilane by effecting reaction between bromobenzene and triethylsilane in the presence of 0.01 to 1 weight percent of dichlorobis(triphenylphosphine) palladium at a temperature within the range of about 150.degree.-200.degree. C.
A method of producing dichloromethylphenylsilane by effecting reaction between bromobenzene and dichloromethylsilane in the presence of 1 to 10% by weight of a catalyst selected from the group consisting of palladium and tris(triphenylphosphine) palladium on a solid carrier at a temperature in the range of about 150.degree.-200.degree. C.
