Embedding Chemistry and Pharmacy Into Sustainability
Angewandte Chemie International Edition, EarlyView.Chemistry and pharmacy provide products and processes that are indispensable for our high living standard. To understand their relationship with sustainability is important to allow them to contribute to sustainability in a sustainable manner. An integrated overview of green, circular, and sustainable chemistry and pharmacy is given and how they have t

A new protocol for the synthesis of 4,7,12,15-tetrachloro[2.2]paracyclophane
Beilstein Journal of Organic Chemistry, 2016 We report a green and convenient protocol to prepare 4,7,12,15-tetrachloro[2.2]paracyclophane, the precursor of parylene D, from 2,5-dichloro-p-xylene. In the first bromination step, with H2O2–HBr as a bromide source, this procedure becomes organic-waste-

Nuclear Versus Side-Chain Bromination of 4-Methoxy Toluene by an Electrochemical Method
, 2014 The electrochemical bromination of 4-methoxy toluene by two-phase electrolysis yields 3-bromo 4-methoxy toluene at first, which subsequently undergoes side-chain bromination to give 3-bromo 4-methoxy benzyl bromide as a final product in 86% yield.

Dynamic Covalent Radical Recombination for the Assembly of Tuneable Responsive Porous Organic Cages
Angewandte Chemie International Edition, EarlyView.Dynamic covalent chemistry (DCC) based on reversible radical recombination enables the assembly of responsive, C─C‐linked organic cages. Substituent‐controlled aryldicyanomethyl radicals form discrete, porous architectures with tuneable topology of Tri2 and Tri4 cages, gas selectivity, chromism, and self‐healing behaviour, establishing radical‐based ...
