摘要

(IO) The product, which usually contains 20-25% of unreacted starting material, is purified by distillation or flash chromatography. The fluorochloropropargyl moiety of 1 is apparent in IR and NMR spectra. For example, IC has umpX= 2250 cm-'(m)(C= C);'H NMR (80 MHz. CDCI,) 6 6.6 (dt, 1 H, J= 1.2, 50.5 Hz, CHFCI, I9F NMR'6b (75 MHz, CDCI,) 6
