Porous graphene nanocages with wrinkled surfaces enhancing electrocatalytic activity of lithium/sulfuryl chloride batteries

Nitrogen-doped graphene nanocages with high surface roughness highly overcome the defect of lithium/sulfuryl chloride batteries, which is attributed to the superior interface properties from the porous graphene layer and N-doping effect.

The Study on Chlorination by Sulfuryl Chloride of Benzene/Pyridine Carboxamides and Carbonitriles

In the chlorination of N-[2-aryl-1-(1-piperidinylcarbonyl)ethenyl]arenecarboxamides, it has been found that a derivative having two methoxy substituents on the arenecarbonyl ring undergoes chlorination on the same ring rather than converting into the expected enamine bond chlorination product. Based on the above results, the chlorination of benzamides/nicotinamides by sulfuryl chloride (SO2Cl2) has been studied. We developed a method of synthesizing aromatic chlorinated compounds by treating aromatic amides or nitriles with SO2Cl2 in dichloromethane at 0oC without catalyst. This is a new mild method and gives good yields, especially when benzene ring is substituted by amide or cyano group together with the alkoxy group.

Chlorination of Conjugated Nitroalkenes with PhICl2 and SO2Cl2 for the Synthesis of α-Chloronitroalkenes

Chlorination of conjugated nitroalkenes with iodobenzene dichloride or sulfuryl chloride to give target α-chloronitroalkenes in good yields is described. Details of the procedure depend on the donating ability of the nitroalkene substituents. The activity of the described chlorinating agents increases in order ‘PhICl2/Py’ < ‘SO2Cl2’ < ‘SO2Cl2/HCl’ with the former producing the best yields for highly donating substrates and the latter for non-activated groups. An autocatalytic role of hydrogen chloride and the chemoselectivity of chlorination were also demonstrated.

Visible-light-promoted hydroxysulfonylation of alkylidenecyclopropanes: synthesis of cyclopropane-containing β-hydroxysulfones

Cyclopropane-containing β-hydroxysulfones and cyclopropyl styrenes have been synthesised from readily available ACPs and sulfuryl chloride via visible-light photoredox catalysis.

Sulfuryl chloride as a functional additive towards dendrite-free and long-life Li metal anodes

With ultrahigh theoretical specific capacity and the lowest redox potential, lithium (Li) metal is regarded as the most promising anode material for the electrochemical energy storage field.

Water-Promoted Chlorination of 2-Mercaptobenzothiazoles

Substituted benzothiazoles play an important role in medicinal chemistry due to their pharmacological properties. Their 2-substituted derivatives are often prepared from 2-chlorobenzothiazoles, which in turn can be synthesized from the 2-mercapto precursor using sulfuryl chloride. In practice, this seemingly straightforward and widely used reaction can be impeded by poor reproducibility and low reaction yields. In this communication, we report that the simple addition of water to the reaction leads to remarkable improvements in reaction efficiency. We attribute this effect to the formation of acid through partial hydrolysis of sulfuryl chloride. This hypothesis is supported by the observation that improved yields were also obtained in the presence of some anhydrous acidic additives. The simple combination of sulfuryl chloride and water reproducibly provides excellent yields for a range of chlorinated products.
