A novel and efficient protocol for oxidation of cumene to cumene hydroperoxide was presented using ambient O2 catalyzed by very simple metalloporphyrins. The selectivity toward cumene hydroperoxide reached 98.3% in the cumene conversion of 28.1% with T(4-COOH)PPCu as a catalyst at 80°C. The origin of the higher performance of T(4-COOH)PPCu was mainly ascribed to the low catalytic performance of copper(II) in the cumene hydroperoxide decomposition, and the ability of T(4-COOH)PP in stabilizing cumene hydroperoxide through hydrogen-bond interactions between them. Compared with current industrial processes and academic research in oxidation of cumene to cumene hydroperoxide with O2, the main superiorities of this protocol were the high selectivity, high conversion, simple catalysts, solvent-free, additive-free and mild conditions which made this work an appealing reference for the industrial oxidation of cumene to cumene hydroperoxide, as well as the oxidative functionalization of other C-H bonds in various hydrocarbons. 2021 World Scientific Publishing Company.

Paragraph 0041-0042, (2020/09/12)
The invention discloses a synthesis method of tetraaryl nickel porphyrin catalyzed by anhydrous aluminum trichloride, which comprises the following step: refluxing aromatic aldehyde, pyrrole and nickel salt in a DMF solvent under the catalysis of anhydrous aluminum trichloride to synthesize tetraaryl nickel porphyrin in one step. The reaction process comprises the following steps: sequentially adding anhydrous aluminum trichloride, aryl aldehyde, pyrrole and nickel salt into DMF (Dimethyl Formamide) while stirring, stopping the reaction after heating reflux reaction for a certain time, cooling, standing overnight near 273K, and carrying out suction filtration to obtain a nickel porphyrin crystal. According to the method, aromatic aldehyde, pyrrole and nickel salt are directly used as raw materials, porphin is not needed, strongly corrosive organic acid is not used as a solvent, high-purity tetraaryl nickel porphyrin is obtained at a high yield under the condition that a complex separation means is not needed, and industrial production is easy to achieve.

Paragraph 0055-0059, (2016/12/12)
The invention discloses a continuous production process of tetraaryl metal porphyrin. The process is as follows: firstly, adding a solvent into a multi-phase reaction separation synchronous reactor, wherein the reactor comprises a stirring reaction tower with a reflux device, and at least two constant-temperature settling towers communicated with the bottom of the stirring reaction tower, and the stirring reaction tower comprises a gas-phase region and a reaction region; during reaction, filling the solvent in the reaction region and the constant-temperature settling towers, adding the reaction material tetraaryl porphyrin and a metal salt into the stirring reaction tower for stirring when a temperature is increased to reach a reflux temperature of the solvent or reacting under the condition of ventilating air, directly settling the tetraaryl metal porphyrin generated by the reaction under gravity action to enter the constant-temperature settling towers until the constant-temperature settling tower is filled up with the tetraaryl metal porphyrin, switching the stirring reaction tower to communicate with the other constant-temperature settling tower filled with the solvent and carrying out the process alternatively to realize continuous production. The continuous production process disclosed by the invention can continuously produce high-purity tetraaryl metal porphin with high yield and low cost.

(Figure Presented) Bowled over: Calix[3]dipyrrins were synthesized from pyrrole and aryl aldehyde precursors by the Lindsey protocol, modified by the presence of a small amount of water. These bowl-shaped macrocycles can accommodate three metal (M) ions such as NiII and CuII in a hexagonal M3O3 manner (see structure; Cu green, N blue, O red, C black).
