Catalytic reforming is a chemical process utilized in petroleum refineries to convert naphtha, typically having low octane ratings, into high octane liquid products, called reformates, which are components of high octane gasoline. In this study, a mathematical model was developed for simulation of semi-regenerative catalytic reforming unit and the result of the proposed model was compared with ...

As a part of our ongoing synthetic quest to expand the frontiers of contemporary medicinal chemistry, we now report an expedient synthesis of a potentially useful bicyclo[1.1.1]pentane building block, 3-(pyrazin-2-yl)bicyclo[1.1.1]pentane-1-carboxylic acid. This report also showcases the application of this motif as a probe in a biological study.

Bicyclo[2.1.1]hexanes (BCHs) represent an intriguing class of structurally rigid hydrocarbons that can serve as the bioisosteres benzenoids in medicinal chemistry. Methods for synthesis BCHs are, however, limiting. Reported herein is a facile via strain-release-driven [2π + 2σ] cycloaddition bicyclo[1.1.0]butanes (BCBs) with alkenes facilitated by pyridine-boryl radical catalyst. The mild react...

The title compound, C(9)H(14)N(2)O, exists in the zwitterionic form in the crystal. The cyclo-octane ring adopts a twisted boat-chair conformation. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into sheets lying parallel to bc. The structure is also stabilized by π-π inter-actions, with a centroid-to-centroid distance of 3.5684 (8) Å.

The title compound, C(22)H(20)Cl(8)O(4), was prepared as part of the synthesis of precursors for the preparation of fluorinated mol-ecular tweezers. The mol-ecule sits on an inversion center, thus requiring that the cyclo-octane ring adopt a chair conformation.

A series of β,β'-bicyclo-3,5-diaryl-BODIPYs were synthesized from the corresponding β,β'-bicyclo-3,5-diiodo-BODIPYs (1a,b) via Pd(0)-mediated Suzuki cross-coupling reactions in 82-92% yields. Subsequent aromatization with DDQ afforded the corresponding β,β'-dibenzo-aryl-BODIPYs, which showed red-shifted absorptions and emissions in the near-IR range. The dibenzo-appended BODIPYs showed characte...
