Usage

General Description

4-methyl-4'-pentyl-1,1'-biphenyl is a chemical compound which belongs to the class of organic molecules known as biphenyls and derivatives. These are organic compounds containing two benzene rings joined by a C-C bond. This particular compound has a methyl group (CH3) attached to the fourth carbon atom on one benzene ring and a pentyl group (C5H11) attached to the fourth carbon atom on the other benzene ring. The pentyl group includes five carbon atoms that are arranged sequentially. Its structure is such that it broadly fits into the category of biphenyls which are usually encountered in the fields of microelectronics and liquid crystals. However, despite its classification, specific information about its uses and properties is not readily available.

Preparation of metal-immobilized methacrylate-based monolithic columns for flow-through cross-coupling reactions

With the aim of developing efficient flow-through microreactors for high-throughput organic synthesis, in this work, microreactors were fabricated by chemically immobilizing palladium-, nickel-, iron-, and copper-based catalysts onto ligand-modified poly(glycidyl methacrylate-co-ethylene dimethacrylate) [poly(GMA-co-EDMA)] monoliths, which were prepared inside a silicosteel tubing (10 cm long with an inner diameter of 1.0 mm) and modified with several ligands including 5-amino-1,10-phenanthroline (APHEN), iminodiacetic acid (IDA), and iminodimethyl phosphonic acid (IDP). The performance of the resulting microreactors in Suzuki?Miyaura cross-coupling reactions was evaluated, finding that the poly(GMA-co-EDMA) monolith chemically modified with 5-amino-1,10-phenanthroline as a binding site for the palladium catalyst provided an excellent flow-through performance, enabling highly efficient and rapid reactions with high product yields. Moreover, this monolithic microreactor maintained its good activity and efficiency during prolonged use.
