Sulphanilic acid as a recyclable bifunctional organocatalyst in the selective conversion of lignocellulosic biomass to 5-HMF
Mirzaei, Hamid M.,Karimi, Babak
, p. 2282 - 2286 (2016)
We herein report an unprecedented integrated process using organic salts as bifunctional organocatalysts under absolutely metal-free conditions for the conversion of a wide range of biomass-derived carbohydrates, cellulose, and even untreated lignocellulose (e.g. straw and barley husk) into 5-hydroxymethylfurfural (5-HMF) in a well-known water/MIBK biphasic solvent system.

An efficient method for the preparation of aryltriethoxy-silanes from arenediazonium tosylate salts has been developed, which expands the substrates of rhodium-catalyzed silylation from iodides, bromides, and triflates to diazonium salts. A new method for hydrodediazoniation has also been explored.
KINETICS AND MECHANISM OF AMINOLYSIS OF PROPARGYL AND 1-METHYL-PROPARGYL ARENESULPHONATES

Kinetic studies were carried out on the aminolysis of propargyl and 1-methylpropargyl arenesulphonates in acetonitrile at 45.0 deg C.The cross-interaction constants, ρxz and βxz, are similar to, but smaller than, those for the SN2 processes at other primary and secondary carbon centers.Compared with the allyl series, the smaller magnitude of ρxz and βxz reflects a looser transition state, which in turn leads to a lower rate despite the greater Taft's ?* value and the lower intrinsic (ΔE0) and thermodynamic barriers (ΔE0).
