A simple method for estimating the contributions of mineral dust to PM 2.5 , PM 10 , or TSP is presented. The method is based on the assumption of external mixing of two types of particles with different PM 2.5 /PM 10 ratios. The method was applied t

Iron salt-catalyzed Friedel-Crafts alkylation of chiral α-aryl alcohols with a trimethylsilyl group was found to proceed with retention of the configuration of the hydroxyl group as a leaving group. The memory of chirality of this system stems from
