| Abstract: | The action of chloromethyl ether on di(2-thienyl)methane, 1, 1-di-(2-thienyl)ethane, 2, 2-di(2-thienyl)propane, 2, 5-bis(dimethyl-2-thienylmethyl)thiophene, and 1, 1, 1-tri(2-thienyl)ethane has given, respectively: 5-chloromethyl -2 -thienylthiophene, 1, 1-bis(5-chloro-methyl-2-thienyl)ethane, 2, 2-bis(5-chloromethyl-2-thienyl)propane, 2, 5-bis(dimethyl-5-chloromethyl-2-thienylmethyl)thiophene, 1-(2-thienyl)-1, 1-bis(5-chloromethyl-2-thienyl)-ethane, and the corresponding amines: 5-diethylaminomethyl-2-thienylthiophene, 1,1-Bis(5-diethylaminomethyl-2-thienyl)ethane, 2, 2-bis(5-aminomethyl-2 -thienyl)propane, 2, 2-bis(5-methylaminomethyl-2-thienyl)propane, 2, 5-bis(dimethyl-5-dimethylaminomethyl-2-thienylmethyl)thiophene, and 2, 8, 8, 14, 20, 20-hexamethyl-2, 14-diaza-3, 2, 3, 2-α-cyclotetrathiene. The reductive desulfonation over Raney nickel of the diacetyl derivatives of 2, 2-bis(5-aminomethyl-2-thienyl)propane and 2, 2-bis(5-methylaminomethyl-2-thienyl)propane has given the diacetyl derivatives of aliphatic amines. |
