Multigram-Scale Synthetic Routes to Solvent-Free CommonSecondary Dialkylphosphines and Chlorodialkylphosphines

Secondary dialkylphosphines and chlorodialkylphosphines are some of the most common starting points in ligand synthesis; however, sourcing these synthons can be troublesome. In this paper, we present scalable synthetic routes to the <i>iso</i>-propyl, <i>tert</i>-butyl, and cyclohexyl derivatives. Detailed experimental procedures are given to allow for ease of synthesis.
