Structure‐Activity Relationships of Glucose‐based PdII‐Bis(NHC) Complexes in a Model Suzuki‐Miyaura Reaction

“…In an analogue pathway as performed for the acetylprotected products, both pivaloyl-and benzoyl-protected starting materials (9 and 10), glucosyl methyl imidazolium salts (11 and 12) and Pd II -bis(NHC) complexes (13 and 14) were synthesized (Scheme 5). The reaction procedures for the introduction of the pivaloyl [27] and benzoyl [28] protecting groups were adapted from known procedures for similar sugars. In general, all yields were in the same regions as for the acetylated products, with the exception of the complexes, whose yields dropped from 96 % (5 a) to 77 % for the pivaloylated complex 13 and to 66 % for the benzoylated complex 14, which is likely explained by the rising steric demand of these groups.…”
