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 ...
