In a further reaction 2-TMS-l,2,3-triazole (q nthesized by silylation of a 1,2,3-triazole can easily be acylated in 1-position using acetic anhydride or acetyl chloride (Scheme 51). Tanaka et al. have intensively studied this reaction using (p-subst)-monophenyl-acetylenes and 14. Their results showed that in this case an electron releasing substituent induces a higher yield whereas it can normally be said the more electron withdrawing a substituent is, the higher the yield in this type of reaction. [Pg.64]
