General description
100 Glass plates 2,5 x 7,5 cm
Application
- MSTFA as an Effective TMS Source for the TMSOTf-Catalyzed Synthesis of Cyclic Acetals: This study demonstrates the utility of 2,2,2-Trifluoro-N-methyl-N-(trimethylsilyl)acetamide as an effective trimethylsilyl donor in the synthesis of cyclic acetals, showcasing its role in facilitating catalyst efficiency and improving reaction conditions for organic synthesis within the realm of green chemistry practices (Radomkit et al., 2024).
