Abstract

" 2'= 60" C; 20 mmol of 1, 2, or 3; 20 mmol of 4; 50 mmol of T= 52" C; V= 30 mL of CH3CN. Molar H, O; 30 mL of CH3CN. ratio of KOH/salt= 1. CMolar ratio of KzC03/salt= 6. respect to 1 (entries 1 and 10). Nevertheless, C-0 does react with the more acidic sulfonium salt 2 (pK,= 7.68), 12 when a very electrophilic aldehyde is used (entries 5, 6, and 8). Under the same conditions, C-200 does not give reaction. The microcrystalline structures of C-0 and ...
