Reaction Mechanism between Phosphonitrilic Chloride Trimer and 2, 6-Di-methyl-p-cresol

Stoichiometry of the reaction between horseradish peroxidase and p-cresol.

Over a wide range of pH horseradish peroxidase compound I can be reduced quantitatively via compound II to the native enzyme by only 1 molar equivalent of p-cresol. Since 2 molar equivalents of electrons are required for the single turnover of the enzymatic cycle, p-cresol behaves as a 2-electron reductant. With p-cresol and compound I in a 1:1 ratio compound II and p-methylphenoxy radicals are...

3-(1,2-Di-p-tolyl­vin­yl)-2-methyl-1H-indole

In the title compound, C(25)H(23)N, the indole unit makes a dihedral angles of 79.03 (5) and 61.82 (4)° with the benzene rings. No classical hydrogen bonds are found in the crystal structure.

2-Methyl-5,6-dinitro­benzimidazolium chloride

In the title compound, C(8)H(7)N(4)O(4) (+)·Cl(-), the cation possesses twofold symmetry, with the twofold axis bis-ecting the 2-methyl-5,6-dinitro-benzimidazolium cation. The methyl H atoms are disordered about this twofold axis and were assigned equal half-occupancies. The chloride anion also lies on a twofold axis. In the crystal, N-H⋯Cl and C-H⋯O hydrogen bonds link the ions to form a three...

REACTION OF 4-METHYL- 1 2,4-TRIAZOLINE- 3,5-DIONE WITH DI AND TRI-SUBSTITUTED STYRENES S.E. Mallakpour* and G.B. Butler**

2,4,6-Triisopropylstryrene was synthesized in a single step via the Witting Reaction from the corresponding aldehyde. The reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(M eTD) was investigated. These reactions are instantaneous at room temperature and lead to the formation of 2: 1 ...
