反应详情

This compound was prepared from 3-(2-methylprop-1-enyl)-2,2-dimethylcyclopropanecarboxylic acid and α-fluoro-3-phenoxybenzylbromide following the procedure described in Example 2 Method B. The product, a colourless oil, was characterised by pmr spectroscopy. Chemical shift δ ppm (solvent CDCl3): 1.24(6H, m, C(CH3)2); 1.70(6H, s, (CH3)2C=); about 1.9(2H, m, cyclopropyl protons); 4.93 and 5.43(1H, 2xd, J=7Hz, vinyl proton); 7.13(1H, d, J=56Hz, CHF); about 7.1(9H, m, aromatic protons).
