AgBF4‐Induced Site‐Selective Synthesis of 4‐Sulfonylindoles in Au‐Catalyzed Cyclization‐Sulfonyl Migration Reactions

Chemistry – A European Journal, EarlyView.
Site‐selective synthesis 4‐suflonylindoles was achieved by a cyclization‐rearrangement strategy by π‐Lewis acidic gold catalysts and the aid of silver cocatalyst. Particularly, the use of 3 equivalents of AgBF4 to SPhosAuCl is crucial for C4‐selective migration of the sulfonyl group.

Deuterium distribution in two major products obtained during the cyclic dimerisation of methyloxirane over acidic molecular sieves [PDF]

, 2006
The ring-transformation reactions of methyloxirane on DZSM-5 and DAlMCM-41 aluminosilicates were studied in a pulse microreactor at 363 K. Cyclic dimerisation was found to be the major reaction pathway. Deuterium distribution in two important products of

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

Chemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

Chemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

SmI2/Sm‐Induced Reductive Silacyclization of Alkene/Diene Derivatives Using Dichlorosilanes or 1,2‐Dichlorodisilanes via Reductive Radical‐Polar Crossover

Chemistry – A European Journal, EarlyView.
A SmI2/Sm‐mediated silacyclization unlocks a concise route to 4–7‐membered silacycles from simple unsaturated substrates and dichlorosilanes/disilanes. The complementary functions of samarium reductants trigger a reductive radical–polar crossover, offering a versatile strategy for constructing multiple Si─C bonds efficiently.
