Yield obtained by GC standard method. b Product isolated by distillation. C Product isolated by column chromatography. cis/trans ratio observed in the formation of 1, 2-diphenyl- lpropene also appears to be the result of some isomerization since higher ratios were observed using ether solvent. 1 For this reason several other tosylhydrazones which would give stable products were tested with the LDA/TMEDA reactant. Table I1 shows the results ...
