Reactions of 3,5-dichloro-2,4,6-trimethyl benzonitrile oxide 241 with fluoro-methyl substituted alkenes 242, bearing a chiral sulfinyl group at -position of the double bond, afford diastereoisomeric 4,5-dihydroisoxazoles 243 and 244 [180] with a stereoselectivity lower than 2 1 (Scheme 110). The authors conclude that the efficiency of allyl sulfoxides to control diastereoselectivity of 1,3-dipolar cycloadditions with nitrile oxides is lower than that of vinyl sulfoxides. [Pg.115]

Perfluorocyclopropene reacts readily with sodium methoxide at low temperature [22] (equation 19) Slow addition of sodium methoxide to 1,2 dichloro-3,3-di fluorocyclopropane yields initially l-chloro-2-methoxy-3,3-difluorocyclopro pane Further addition of methanol produces probably a ketal Opening of the cyclopropane ring gives an ortho ester that undergoes facile hydrolysis during the workup to form (Z)-methyl 2-fluoro-3-chloroacrylate [23] (equation 20) A per-fluorocyclobutene dimer is also very reactive and undergoes an easy SN2 displacement on treatment with ethanol [24] (equation 21)...

Both hydrogen and chlorine may be displaced by lithium. In this case, hydrogen is displaced preferentially to give l,2-dichloro-2-fluorovinyllith-ium. The organometallic compound is then treated with acetone, and the intermediate is decomposed with water to afford 3,4-dichloro-4-fluoro-2-methyl-3-buten-2-ol, l,2-dichloro-2-fluorovinyldimethylcarbinol thus, X = Cl [111].

The majority of pyrethroid insecticides have low volatilities. The heavily used synthetic pyrethroid permethrin is classified as nonvolatile on the basis of its vapor pressure (1.3 x 10 kPa at 20 °C) and is rarely found in indoor air. However, it has recently been reported to be the major pesticide residue found in house dust (USEPA, 2000d). Cyper-methrin [( )-a-cyano-3-phenoxybenzyl-( )-cA,frani -3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate] and cyfluthrin [cyano(4-fluoro-3-phenoxy-phenyl)methyl 3-(2,2-dichloro-ethenyl)-2,2-dimethylcyclopropanecarboxylate] are two other low-volatility pyrethroids commonly used for indoor flea and cockroach control.
