Published: August 2023

Alkynylsilanes are significant structural units frequently used in synthetic chemistry, medicinal chemistry, functional materials, and life sciences. Herein, we report a method for using a hydrogen atom transfer (HAT) strategy in combination with visible-light-driven photocatalysis to achieve a direct coupling reaction between benzene sulfonyl acetylene and tertiary silanes, and a diverse alkynylation of hydrosilanes in the presence of reactive groups was achieved with this strategy. It is important to note that dihydroalkyl/aryl silanes are also suitable for the protocol of HAT photocatalytic of 4CzIPN and quinuclidine.

Alkynylsilanes are one kind of essential synthetic block in organic chemistry. The established synthetic routes retain some drawbacks regarding harsh reaction conditions or expensive/rare metal catalysts. Herein, we report a method for iron-catalyzed, visible-light-induced alkynylation of hydrosilanes to produce value-added silicon compounds.

Ligand development plays an essential role in the advance of homogeneous catalysis. Tridentate, meridionally coordinating ligands, commonly termed pincer ligands, have been established as a privileged class of ligands in catalysis because they confer high stability while maintaining electronic tenability to the resulting metal complexes. Pincer ligands containing "soft" donors such as phosphines are typically used for late transition-metal ions, which are considered "soft" acids.

The synthesis, structural characterization, and reactivity of the first two-coordinate cobalt complex featuring a metal-element multiple bond [(IPr)Co(NDmp)] (4; IPr=1,3-bis(2',6'-diisopropylphenyl)imidazole-2-ylidene; Dmp=2,6-dimesitylphenyl) is reported. Complex 4 was prepared from the reaction of [(IPr)Co(η(2) -vtms)2 ] (vtms=vinyltrimethylsilane) with DmpN3 . An X-ray diffraction study revealed its linear C-Co-N core and a short Co-N distance (1.

An indium triiodide catalyst promoted the direct transformation from esters to β-hydroxycarbonyl compounds using hydrosilanes and silyl enolates by a one-stage process. Various esters were applicable, and the high chemoselectivity of this system brings compatibility to many functional groups: alkenyl, alkynyl, chloro, and hydroxy.
