[reaction: see text] A short and convergent synthesis of 2-aryl-6-chloronicotinamides via regioselective Suzuki coupling of 2,6-dichloronicotinamide with aryl boronic acids is described. Regioselectivity was achieved by chelation of the palladium(...

The objective of this study was to investigate the levels of Escherichia coli on different sites of turkey carcasses by sponge sampling using a 50 cm2 template. The breast, thigh, back, and cavity sites were sampled to determine which sites would...
