This reagent was originally prepared by Conrad Willgerodt by reacting iodobenzene with a mixture of acetic acid and peracetic acid: C6H5I + CH3CO3H + CH3CO2H → C6H5I(O2CCH3)2 + H2O PIDA can also be prepared from iodosobenzene and glacial acetic acid: C6H5IO + 2 CH3CO2H → C6H5I(O2CCH3)2 + H2O Web1,2-Bis (triethoxysilyl)ethane (BTESE) is a silsesquioxane precursor which is mainly used in the preparation of mesoporous organic materials. It can tune silica networks which …
