Abstract
Herein, we present the first, one-step, direct synthesis of unsymmetric phosphorotrithioates through a process involving sequential coupling of 1,1-dichloro-N,N-diethylphosphanamine with thiols and sulfenyl chloride. This method showcases excellent functional group tolerance, substrate compatibility, and mild reaction conditions, offering a streamlined approach for the challenging phosphorotrithioate synthesis. Additionally, the applicability of this method can be extended to the synthesis of mixed phosphoroselenodithioates.

Abstract
In this study, we report a novel and efficient one-pot synthesis of mixed phosphorotrithioates under mild conditions at ambient temperature, obviating the requirement for supplementary additives. The method's versatility stems from its utilization of diverse thiols as nucleophilic reactants, 1-chloro-N,N,N',N'-tetraisopropylphosphanediamine [bis(diisopropylamino)chlorophosphine] as the phosphorus precursor, and various sulphenyl chlorides as sources of electrophilic sulfur. Notably, our investigation extends beyond mixed phosphorotrithioates to encompass the synthesis of phosphoroselenodithioates, underscoring the broad applicability of this synthetic protocol.

Abstract
Reported herein is the ligand-enabled gold-catalyzed alkenylation and arylation of phosphorothioates using alkenyl and aryl iodides. Mechanistic studies revealed a crucial role of the in situ generated Ag-sulfur complex, which undergoes a facile transmetalation with the Au(iii) intermediate, thereby leading to the successful realization of the present reaction. Moreover, for the first time, the alkenylation of phosphoroselenoates under gold redox catalysis has been presented.

Abstract
A simple and efficient protocol for the synthesis of arylmethyl substituted organophosphorus compounds is presented. This method involves the reaction of diphenyl phosphite with aldehydes in the presence of BF3-Et2O. In this method, BF3-Et2O plays a dual role, as it facilitates the generation of both hydrophosphonylated intermediate and phenol from diphenyl phosphite. A significant feature of this approach is its tolerance to the presence of external nucleophiles, such as phenol, aliphatic thiols, indole and 3-methylanisole. The simplicity of the reaction conditions and the high yields achieved make this method promising for applications in areas where phosphonate compounds are of interest.

Abstract
Selenium, originally described as a toxin, turns out to be a crucial trace element for life that appears as selenocysteine and its dimer, selenocystine. From the point of view of drug developments, selenium-containing drugs are isosteres of sulfur and oxygen with the advantage that the presence of the selenium atom confers antioxidant properties and high lipophilicity, which would increase cell membrane permeation leading to better oral bioavailability. In this article, we have focused on the relevant features of the selenium atom, above all, the corresponding synthetic approaches to access a variety of organoselenium molecules along with the proposed reaction mechanisms. The preparation and biological properties of selenosugars, including selenoglycosides, selenonucleosides, selenopeptides, and other selenium-containing compounds will be treated. We have attempted to condense the most important aspects and interesting examples of the chemistry of selenium into a single article.

Abstract
Herein, we present the first mild, one-step direct synthesis of mixed phosphorothioates through selective generation of O-P(O)-S bonds at rt under additive-free condition. Further, reactions of different model natural products with 1,1-dichloro-N,N-diisopropylphosphanamine helped to present an alternative dimerization strategy. The synthetic utility of the methodology was extended for the synthesis of mixed phosphoroselenoates as well. The potential of the reaction was further demonstrated for the synthesis of mixed phosphorothioate bearing two different alcohols.
