Strongin 10.1021/jo051002a.s005 https://acs.figshare.com/articles/dataset/A_Convenient_Preparation_of_Xanthene_Dyes/3272203 A facile synthetic route utilizing readily available reagents affords a series of regioisomerically pure xanthene dye derivatives. Advantages include relatively mild conditions and good to excellent yields. Nonpolar, highly crystalline intermediates are isolable by standard chromatographic techniques. The intermediates are in the requisite xanthene oxidation state, thus avoiding the need for relatively inefficient oxidation chemistry and/or harsh conditions. During the course of this work, a new boron-mediated 1,2-aryl migration reaction was discovered. 2005-08-19 00:00:00 Convenient Preparation migration xanthene oxidation state technique intermediate Advantages isolable series Nonpolar regioisomerically xanthene dye derivatives reagent Xanthene Dyes yield oxidation chemistry aryl
