2009 journal article
In-situ NMR studies of isobutane activation and exchange in zeolite beta
SOLID STATE NUCLEAR MAGNETIC RESONANCE, 35(2), 100–103.
author keywords: Isobutane; Alkane activation; C-H bond activation; In-situ NMR; Catalysis; Zeolite; Mechanism
MeSH headings : Butanes / analysis; Butanes / chemistry; Computer Simulation; Magnetic Resonance Spectroscopy / methods; Models, Chemical; Models, Molecular; Molecular Conformation; Zeolites / analysis; Zeolites / chemistry
TL;DR:
Estimation of true activation energies using heat of adsorption data from the literature combined with the experimentally measured apparent E(a) suggests that the true activation barrier differs by only 6-7kJ/mole in the two catalysts.

2006 journal article
Weak hydrogen bonding can initiate alkane C-H bond activation in acidic zeolites
JOURNAL OF PHYSICAL CHEMISTRY B, 110(42), 20762–20764.
TL;DR:
The mechanism described in this contribution demonstrates that weak C-H to O hydrogen bonding leads to complexes at the zeolite acid site that can facilitate C- H bond activation.

2004 journal article
Identification of an adsorption complex between an alkane and zeolite active sites
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 126(36), 11144–11145.
TL;DR:
Direct observation of the Bronsted acid site signal in an active zeolite catalyst following adsorption of stoichiometric quantities of isobutane reveals the presence of a specific Adsorption complex, proposed as a route to C-H bond activation in solid acids.
