Journal ArticleDOI
Visible light catalyzed methylsulfoxidation of (het)aryl diazonium salts using DMSO
TL;DR: The visible light catalyzed methylsulfoxidation of (het)aryl diazonium salts using DMSO is illustrated and provides aryl methyl sulfoxides in excellent yields under mild reaction conditions.
Journal ArticleDOI
Synthesis of 3-carbonyl pyrazole-5-phosphonates via 1,3-dipolar cycloaddition of Bestmann–Ohira reagent with ynones
TL;DR: This work explores the hitherto unexplored reactivity of ynones as dipolarophiles with Bestmann–Ohira reagent to find di-ynones and molecules possessing both ynone and enone functionalities provide only monocycloaddition products.
Journal ArticleDOI
Substituent controlled reactivity switch: selective synthesis of α-diazoalkylphosphonates or vinylphosphonates via nucleophilic substitution of alkyl bromides with Bestmann–Ohira reagent

TL;DR: A substituent controlled nucleophilic displacement of alkyl bromides with Bestmann-Ohira reagent yielding either dimethyl diazoalkylph phosphonates or (E)-vinylphosphonates is reported, which could be readily converted into corresponding (E-vinyl phosphonate in the presence of Cu following nitrogen elimination in quantitative yields.
Journal ArticleDOI
Visible light catalyzed Mannich reaction between tert-amines and silyl diazoenolates.
Mukund M. D. Pramanik,Mukund M. D. Pramanik,Savita B. Nagode,Savita B. Nagode,Ruchir Kant,Namrata Rastogi,Namrata Rastogi +6 more
TL;DR: The present work documents the α-C-H functionalization of tertiary amines via the visible light catalyzed Mannich reaction with silyl diazoenolates, affording stable ammonium ylides in high yields.
Journal ArticleDOI
Synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylbenzotriazole-mediated acylation of a diazomethyl anion.
TL;DR: A method for the synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylation of corresponding diazomethyl anions with N-acylbenzotriazoles is reported.
