All reactions performed under a nitrogen atmosphere.
All reactions carried out with 10 mol% of catalyst.
Conversion was measured by 1H NMR analysis (400 MHz) of the unpurified reaction mixture; homodimer was also present (see the Supporting Information).
Determined by GLC analysis of the purified material; see the Supporting Information for details.
