Keywords Merriﬁeld resin Selective oxidation Alcohols Ferrocene Reusability Introduction Selective oxidation of alcohols into aldehydes is a ubiquitous and pivotal process in organic chemistry [1–4]. Traditionally, high-valent metal oxides of chromium, manganese and ruthenium are widely employed for this purpose [5–8]. Insights into these homogeneous catalytic systems have revealed some serious problems, such as over-oxidation of aldehydes to carboxylic acid, the use of hazardous terminal oxidants, drastic reaction conditions, tedious work-up procedures and generation of signiﬁcant amounts of toxic waste products. The covalent immobilization of these reagents on solid supports has been carried out to alleviate aforementioned problems and provide an attractive alternative in organic synthesis in view of the selectivity and associated ease of manipulation [9–14]. A variety of other reagents, such as oxone , calcium hypochlorite , 2-hydroperoxyhexaﬂuoro-2-propanol , vanadium , Cu-NHC-TEMPO , nano structured rutile TiO , palladium , choline peroxydisulphate , nickel phosphine complexes , In(NO ) in 3 3 [C mim][FeBr ], derivatives of 1-acetoxy-1,2-benziodoxole-3(1H)-one , 12 4 sym-collidinium chlorochromate (S-COCC) , Ag-NHC complex , etc. have been used for selective
