Kinetics of phenol alkylation with tert-butyl alcohol using supported ionic liquid catalyst

Friedel-Crafts alkylation of Phenol using Ionic Liquid as Catalyst

The first non-acid catalytic synthesis of tert-butyl ether from tert-butyl alcohol using ionic liquid as dehydrator.

Methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and isopropyl tert-butyl ether (IPTBE) have been synthesized for the first time over a non-acid ionic liquid as catalyst and dehydrator with high conversion (> 90%) and selectivity (> 90%) under mild conditions.

2,6-Di-tert-butyl-4-(methoxy­meth­yl)phenol

The title compound, C(16)H(26)O(2), was easily obtained in high yield when 4-bromo-methyl-2,6-di-tert-butyl-phenol was reacted with methanol. There are two independent mol-ecules in the asymmetric unit. The meth-oxy group in each of the independent mol-ecules was found to be disordered, with site-occupation factors of 0.8728 (18)/0.1272 (18) and 0.8781 (17)/0.1219 (17).

2,6-Di-tert-butyl-4-(dimethyl­amino­meth­yl)phenol

The title compound, C(17)H(29)NO, is an important hindered phenol derivative. The asymmetric unit contains two mol-ecules. Molecules inter-act through O-H⋯N hydrogen bonds to form a tetramer arranged around a twofold rotation axis.

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
