3- Bromoethyl phenyl ether

This mechanism for -elimination is supported by the fact that other processes which would be expected to produce carbanions beta to groups easily displaced also cause elimination to occur. It is well known that Grignard and Wurtz reactions of 0-haloethers lead to olefins. Tetra-hydrofurfuryl chloride, for example, gives 4-pentene-l-ol on treatment with sodium,8 and 0-bromoethyl phenyl ether yields phenol and ethylene4 when it is allowed to react with magnesium in dry ether. Presumably the mechanisms are ...

The majority of 2-alkyl-5-aryl- 1,3,4-oxadiazoles can easily be cleaved in mineral acid solution to give the corresponding diacid hydrazides. 2-(a-Bromoethyl)-5-phenyl-l,3,4-oxadiazole is hydrolyzed so easily that even during the synthesis from l-a-bromopropionyl-2-benzoylhydrazine, on treating the reaction mixture with water, partial hydrolysis occurs to give the diacid hydrazide or even hydrazine.19 This can be eliminated in the synthesis by among other means the use of petrol ether in place of water. The 2-bromomethyl-5-aryl-...
