Usage

General Description

2-(naphthalen-2-yl)-1,3-dithiolane, also known as diniconazole, is a synthetic compound used primarily as a fungicide in agricultural applications. It belongs to the class of chemicals known as dithiolanes, which are organic compounds containing a five-membered ring with two sulfur atoms and one oxygen atom. Diniconazole is commonly used to control a wide range of fungal diseases in crops such as cereals, oilseeds, fruits, vegetables, and ornamental plants. It works by inhibiting the biosynthesis of ergosterol, a vital component of fungal cell membranes, ultimately leading to the disruption of fungal growth and reproduction. Diniconazole is considered to have low acute toxicity to mammals and beneficial insects, making it a popular choice for integrated pest management programs.

Sulfur-Directed Ligand-Free C-H Borylation by Iridium Catalysis

An iridium-catalyzed ortho C-H borylation reaction directed by cyclic dithioacetal moiety is disclosed. A series of borylation products were obtained in moderate to good yields under mild conditions in exclusive mono- and ortho-regioselectivity. Thus, the 1,3-dithiane or 1,3-dithiolane group serves as a remarkable effective directing group for C-H borylation without any ligand assistance. The further transformations of the borylation products are also carried out to change boryl group to other functional groups.

One-pot two-step conversion of aromatic carboxylic acids and esters to aromatic aldehydes via indium-catalyzed reductive thioacetalization and desulfurization

Described herein is that a new approach to a one-pot two-step conversion of aromatic carboxylic acids/esters to aromatic aldehydes, in which indium(III) iodide effectively catalyzes both the first reductive thioacetalization of carboxylic acids and a subsequent desulfurization of the in-situ formed thioacetal intermediates leading to aldehydes.

B(C6F5)3-Catalyzed Hydrodesulfurization Using Hydrosilanes - Metal-Free Reduction of Sulfides

B(C6F5)3-catalyzed hydrodesulfurization of carbon-sulfur bonds was achieved using triethylsilane as the reducing agent. The corresponding products were obtained in good yields under mild reaction conditions. This protocol could be applied to the reduction of sulfides, including benzyl and alkyl sulfides and dithianes, with high chemoselectivities. (Chemical Equation Presented).
