Triazolinediones as Highly Enabling Synthetic Tools
Triazolinediones (TADs) are unique reagents in organic synthesis that have also found wide applications in different research disciplines, in spite of their somewhat "exotic" reputation. In this review, we offer two case studies that demonstrate the possibilities of these versatile and reliable synthetic tools, namely, in the field of polymer science as well as in more recently emerging applications in the field of click chemistry. As the general use of triazolinediones has always been hampered by the limited commercial and synthetic availability of such reagents, we also offer a review of the available TAD reagents, together with a detailed discussion of their synthesis and reactivity. This review thus aims to serve as a practical guide for researchers that are interested in exploiting and further developing the exceptional click -like reactivity of triazolinediones in various applications
An efficient method for selective deprotection of trimethylsilyl ethers, tetrahydropyranyl ethers, ethylene acetals and ketals under solvent-free conditions
1251-12561-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane
dichromate (BAABOD) is a useful reagent for the selective cleavage of trimethylsilyl
ethers, tetrahydropyranyl ethers, ethylene acetals and ketals to their corresponding
alcohols, aldehydes and ketones. This method is very simple and efficient and the
reaction has been carried out under solvent-free conditions in the presence of
anhydrous aluminium chloride
