Pu Using the Grignard Reaction to Prepare Triphenylmethanol By: Alexis Huddleston Abstract Grignard reagents are considered to be organometallic reagents and are therefore usually strong Lewis bases and function as good nucleophiles. * Chloropicrin can affect you when breathed in. Chloropicrin was discovered in 1848 by Scottish chemist John Stenhouse. 2nd ed. When heated to decomposition, it emits highly toxic fumes of chlorine gas and nitrogen oxides [Sax, 9th ed., 1996, p. 821]. For soil fumigation and wood treatment, Chloropicrin is packaged in DOT 4BW240 steel cylinders and bulk tanks, which may be pressurized. Chloropicrin is formed in water by the reaction of chlorine with humic acids, amino acids, and nitrophenols. The presence of nitrates increases the amount formed (6). Chloropicrin has been detected in drinking-water; however, in the presence of reducing agents, it is converted into chloroform (6). Chloropicrin fumigants dissipate quickly under standard application temperatures, so damage to the target crop due to residual chemical in the soil is unlikely.
