موضوع به انگلیسی:Establishment of salicylic acid derived silylation reagents for protection of
alcohols
بخشی از متن:In this work, we describe salicylic acid derived 2‐[(trimethylsilyl)oxy]‐benzoic acid methyl ester (TMSSME)
and its TBDMS‐ (TBDMSSME) and TIPS‐analogous (TIPSSME) as novel silylation reagents to furnish silyl ethers
from alcohols. Silylation readily occurred in yields of 55–97% with TMSSME for a variety of aliphatic and aromatic
alcohols. The reaction was effectively catalyzed by Dowex (50Wx8) under mild reaction conditions.
Silylation with the corresponding TBDMS‐ and TIPS‐reagents, however, required modified reaction conditions
and only occurred on primary alcohols in good yields
