Addition of HCl to 3,3-dimethyl-1-butene and reaction of HCl with 3,3-dimethyl-2-butanol give the same product. Explain, View Solution Explain why the addition of HI to 3,3-dimethylbut-1-ene gives 2-iodo-2,3-dimethylbutane as the major product and not the 2-iodo-3,3-dimethylbutan...
The residue is triturated with 2N. HCl, extracted with CH2Cl2, the extract dried, evaporated, the residue stirred with ethyl acetate, filtered and this residue filtered off to give 1-(p-beta-ethylaminoethoxyphenyl)-1,2-trans-diphenylprop-1-ene HCl. (m.p. 206-208 deg.C.)....
eliminating HCl in the conventional manner.The butanedial-bis- acetals and butenedial-bis- acetals are valuable intermediates through which the trans- 3-methyl-but-2-ene-1,4-dial-1-acetals, which are sought- after products for terpene syntheses, can be obtained in an industrially particularly...
