摘要

Results Synthesis of 4, 4-Dimethyl-l, l-diphenyl-1, 2-pentadiene (1) and C3-Deuterated Derivative 1-d Deprotonation of 4, 4-dimethyll, l-diphenyl-2-pentyne (3) using 1 equiv of n- butyllithium in THF at-5 OC produced a red-colored solution from which 1 was isolated after acidification with glacial acetic acid at-78" C. Use of either conventional silica gel column chromatography or medium pressure liquid chromatography (MPLC) effected separation ...
