p- (β-Bromoethyl) benzyl chloride was treated with sodium alcoholate at room temperature to obtain p-vinylbenzyl ether, which could be polymerized in bulk using 2, 2'-azobisisobutyronitrile as an initiator. BrCH2 CH2-_??_-CH2 CINaOR→CH2=CH-_??_CH2 OR→ [-CH-CH2-_??_-CH2OR] n R=C2H5, CH3, (CH2) 2CH3, CH (CH3) 2, CH2CH=CH2, (CH2) 3CH3, CH2CH (CH3) 2 Sodium tert-butyrate failed to give the expected tert-butyl ether. Instead, p-chloromethylstyrene was the only product isolated. Using sodium mercaptide under analogous conditions, p-vinylbenzyl sulfide was synthesized, from which a new polymer was obtained as follows ; BrCH2CH2-_??_-CH2ClNasR→BrCH2CH2-_??_-CH2SRKOH→CH2=CH-_??_-CH2SR→ [-CH-CH2-_??_-CH2SR] n R=C2H5, (CH2) 2CH3
p-Nitrobenzhydroxamoyl chloride was treated with ammonium thiocyanate in methanol at room temperature for 3 days to afford p-nitrophenylthiourethane (3), though the similar treatment of 5-nitro-2-furylhydroxamoyl chloride afforded 3- (5 nitro-2-furyl) -5-imino-1, 2, 4-oxadiazole (2). Similar treatment of p-, m-nitrobenzhydroxamoyl chloride and 5-nitro-2-furylhydroxamoyl chloride with potassium cyanate afforded the corresponding oxadiazolones (4).
