Direct Mechanocatalysis: Palladium as Milling Media and Catalyst in the Mechanochemical Suzuki Polymerization

“…Them aterials were also investigated via Raman spectroscopy ( Figure 1C and Figure S3) where characteristic bands were observed at 1220 cm À1 (n intra-ring (C À C)), 1280 cm À1 (n inter-ring (CÀC)), and 1600 cm À1 (d in-plane (CÀH)). [33] Fitting the spectral peaks by aLorentzian function [34] and comparing the intensities of the peaks at 1220 cm À1 and 1280 cm À1 [35] validated qualitatively the high degree of polymerization as Scheme 1. Mechanochemical Suzuki polymerization reaction of 4-bromophenylboronic acid to give poly(para-phenylene)( PPP).…”
