Methanol → Perhydroxyl radical

Participants

Reaction Steps

A portion of the beads produced (20 g) were swelled in 60 ml of a solution of dichloromethane and methanol (equal volume ratios) and 80 g of peracetic acid solution obtained from 31% hydroperoxide and acetic anhydride, were added drop by drop with cooling and the reaction was continued for 4 hours at room temperature in order to oxidize triphenylphosphine units. The beads containing triphenylphosphine oxide units were dipped into 100 ml of monochlorobenzene containing 10 g of oxalic chloride and the solution was stirred for 5 hours at room temperature so as to convert triphenylphosphine oxide units into triphenylphosphine dichloride units. The beads were washed with dichloromethane (CH2Cl2) completely and dried. Yield of the beads was 24.9 g. The beads produced contained pendant diphenylphosphine dichloride groups and had the structural formula: ##STR9##
