Abstract: Here we report the first base-metal catalyzed dehydrogenative coupling of primary (aromatic, heteroaromatic, and aliphatic) and secondary alcohols with methyl-N-heteroaromatics to form various C(sp3)-alkylated N-heteroaromatics. The reaction is enabled by Earth abundant, non-precious NiBr2 as… read more here.

DOI: 10.3390/polym14245560
Abstract: A polymer model exhibiting heterogeneous Johari–Goldstein (JG) secondary relaxation is studied by extensive molecular-dynamics simulations of states with different temperature and pressure. Time–temperature–pressure superposition of the primary (segmental) relaxation is evidenced. The time scales of… read more here.
