Storage … WebbThe relatively volatile products (3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j and 3v) were not isolated and their yields were determined by 19F NMR measurement in CDCl3 of the reaction mixture. For the products reported with 19F NMR yields, PhOCF3 (1.0 equiv) was added to the reaction mixture as internal standard added after the reaction completed.
