Selective Reactivity of sp3 and sp2 Carbanions of 1-Substituted 1,2,4-Triazoles. A Comparative Approach
摘要:
The regioselectivity of lithiation reactions of 1-n-alkyl-, 1-allyl-, and 1-propargyl-1H-1,2,4-triazoles was studied in terms of the products formed by sequential treatment with BuLi and a range of electrophiles.
