We report herein P(III)-directed C–H bond alkenylation of (dialkyl)- and (diaryl)biarylphosphines using internal alkynes. Chloride-free [Rh(OAc)(COD)]2 acts as a better catalyst than commercially available [RhCl(COD)]2. Conditions were developed to control the mono- and difunctionalization depending on the alkyne stoichiometry. One of these novel bisalkenylated (dialkyl)biarylphosphines was employed

The present article describes a series of 21 N-(aryl)-2-thiophen-2-ylacetamides, which were synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis, and the activity expressed as the minimum inhibitory concentration (MIC) in mu g/mL. The compounds 2, 3, 7, 8,11, 12, 15,16, and 20 exhibited activity between 25 and 100 mu g/mL and could be a good start point to find new lead compounds in the fight against multidrug resistant tuberculosis.
