Abstract
<p class="first" id="P1">A concise synthesis of monobenzofused 1,4-azaborine phosphine
ligands (Senphos) is
described. These Senphos ligands uniquely support Pd-catalyzed
<i>trans</i>-selective hydroboration of terminal and internal 1,3-enynes to furnish
corresponding
dienylboronates in high efficiency and diastereoselectivity. X-ray structural analysis
of the Senphos–Pd(0) complex reveals a
<i>κ</i>
<sup>2</sup>-
<i>P</i>-
<i>η</i>
<sup>2</sup>-BC coordination mode, and this isolated complex has been shown to serve
as a competent
catalyst for the
<i>trans</i>-hydroboration reaction. This work demonstrates that the expanded chemical
space provided
by the BN/CC isosterism approach translates into the functional space in the context
of stereoselective catalytic transformations.
