C-H Bond Formation
The preparation of alkenyl halides of any length from inexpensive starting reagents is reported. Standard organic transformations were used to prepare straight-chain α-olefin halides in excellent overall yields with no detectable olefin isomerization and full recovery of any unreacted starting material.

Addition of in situ generated Schwartz reagent to widely available isocyanates enables a chemoselective, high-yielding, and versatile synthesis of variously functionalized formamides. The reaction tolerates the presence of sensitive functionalities (esters, nitro groups, nitriles, alkenes).
