Abstract
A metal-free hexafluoroisopropanol-mediated hydro-phosphorothiolation of styrenes and donor-acceptor cyclopropanes with S-hydrogen phosphorothioates in a Markovnikov fashion has been developed under ambient reaction conditions to afford a library of S-alkyl phosphorothioates. Notably, this strategy provides a simple and efficient way to produce biologically significant kitazin and iprobenfos derivatives. Mechanistic studies disclose that the reaction proceeds through a carbocation intermediate.

Abstract
A photoredox/copper-catalyzed cascade radical cyclization/phosphorothiolation reaction of N-allylbromoacetamides and P(O)SH compounds has been established. A broad range of novel nonfluorine- or difluoro-substituted 2-pyrrolidinones bearing the C(sp3)-SP(O)(OR)2 moiety can be conveniently constructed in moderate to good yields under mild conditions. Importantly, most of the tested phosphorothiolated 2-pyrrolidinones showed potent inhibitory effects toward both AChE and BChE.

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
A cyanoalkyl-hydroxylation reaction of aryl alkenes has been successfully devised, employing ferrocene as a catalyst for the addition of a cycloketone oxime ester and H2O across the double bond of the alkene. This environmentally friendly approach employs a solvent mixture consisting of water and demonstrates redox neutrality, along with exceptional regio- and chemoselectivity, leading to the formation of diverse distal hydroxy-nitrile compounds. Moreover, this research presents noteworthy contributions in terms of late-stage functionalization of complex molecules and offers valuable insights into the mechanistic aspects of the reaction.

Abstract
A metal-, chloride reagent and base-free thiophosphorylation reaction of in situ formed ortho-quinone methide (o-QM) to synthesize functionalized thiophosphates has been developed. The reaction is an atom-economical process, producing water as the sole byproduct. (EtO)2P(O)SH functions as both a Brønsted acid and nucleophilic thiolate to produce the o-QM intermediate and the thiophosphate product, respectively. The aza o-QMs were also successfully thiophosphorylated in the presence of catalytic TsOH to form sulfonamido thiophosphates.

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.

Abstract
A photoredox and copper-catalyzed fluoroalkylphosphorothiolation of activated and unactivated alkenes via a radical relay mechanism is reported. By employing fluoroalkyl halides as radical precursors and P(O)SH or P(S)SH compounds as coupling partners, a wide range of β-monofluoroalkyl-, -difluoroalkyl-, -trifluoromethyl-, or -perfluoroalkyl-substituted S-alkyl phosphorothioates and phosphorodithioates can be easily constructed under mild conditions with good functional group tolerance. Furthermore, this modular reaction system can be successfully applied to late-stage functionalization of bioactive molecules.
