Product distribution from the donor oligomerization reaction shown in Scheme 3. (a) LCMS analysis of the crude reaction mixture using a Hichrom C8C18 column with a water/THF (0.1% formic acid) solvent system. (b) Preparative HPLC separation of donor homo-oligomers using a HIRBP-6988 prep column with a water/THF solvent system. Samples were prepared in DMSO, UV/vis absorption was measured at 290 nm, and the peaks identified by MS are labeled with retention time in minutes. dba = dibenzylideneacetone.
