“…In recent years, organometallic complexes containing siloxane functionality have great interest owing to their usefulness to bind covalently with hydroxyl group available on supported materials [1][2][3][4][5][6]. Several reports describing the molybdenum complexes with siloxane functionality present either in ligand center or metal centre, which were further heterogenized on the surface of silica has shown promising catalysts for various oxidation reactions [6][7][8][9][10][11][12][13].…”

“…Similarly, siloxane functionalized ruthenium and rhenium complexes are heterogenized on mesoporous molecular sieve surface has been applied for cyclo-propanation and epoxidation respectively [14,15]. However, syntheses of first row transition metal complexes containing siloxane functional group are rare [3][4][5]. In addition, it is well known that these metal complexes are potential substitution for expensive rare earth and late transition metal catalysts.…”

Cobalticinium complex containing siloxane moiety on ligand center was first time synthesized, characterized and heterogenized on the surface of SBA-15 molecular sieves. FT-IR and 29 Si-MAS-NMR spectrum evidence the successful grafting of the cobalt complex on the surface of SBA-15. N 2 sorption isotherm of cobalticinium complex grafted sample showed the decrease in surface area, pore volume, further confirms the presence of complex inside the channel of mesoporous SBA-15. The heterogenized complex exhibited promising activity for oxidation of alcohols with good selectivity of ketone. Further the catalytic activity remains intact after two recycles. Graphical Abstract Cobalticinium complex possessing siloxane functionality was prepared first time and heterogenized on SBA-15 surface. The resultant materials showed as promising recyclable heterogeneous catalyst for oxidation of alcohols.
