Silica‐supported γ‐(2,2′‐dipyridyl)–aminopropylsiloxane‐methyltrioxorhenium complex was prepared and characterized by IR. The complex with an Re content of 0.45 mmol/g was an effective catalyst for the oxygenation of diphenyl methane when decahydronaphthalene was used as solvent. Decahydronaphthalene was a co‐reductant for the oxygenation of diphenyl methane. The suitable reaction temperature was 100°C. The yield of diphenyl ketone can amount to 70.8% with 84.1% selectivity within 11 hr. Copyright © 1999 John Wiley & Sons, Ltd.
