WebAug 18, 2024 · As a novel alkane isomerization catalyst, namely CoH/Hβ, was prepared by the reduction of CoH (P (OPh) 3) 4, which was pre-impregnated on Hβ as support. The as-prepared CoH/Hβ catalyst was structurally compared with CoH (P (OPh) 3) 4, CoH (P (OPh) 3) 4 /Hβ via FT-IR, TPR, SEM, XRD and other techniques. WebDensity functional theory calculations predict a new mechanistic pathway involving charged intermediates for ether cleavage in aryl methyl ethers. Moreover, these calculations predict that one equivalent of BBr can cleave up to three equivalents of anisole, producing triphenoxyborane [B (OPh) 3 3
