N-arylation of ferrocenyl 2,4-thiazolidinedione conjugates via copper-catalysed Chan-Lam cross coupling reaction with aryl boronic acids and their optoelectronic properties

20-Jun-2018 | Rajiv Trivedi; Dilip N Shinde; Venkata Suman Krishna Jonnadula; Giribabu Lingamallu; Sridhar Balasubramanian; Parag ..., New Journal of Chemistry, 2018

A copper catalyzed Chan-Lam type N-arylation protocol has been applied to achieve moderate to good yields of N-arylated ferrocenyl 2,4 thiazolidinedione conjugates. A general and mild strategy has been developed for the cross-coupling of arylboronic acids and ferrocenyl 2,4 thiazolidinedione ...

Boronic acids as molecular inks for surface functionalization of polyvinyl alcohol substrates

26-May-2018 | Ryuhei Nishiyabu; Miku Tomura; Tomo Okade; Yuji Kubo, New Journal of Chemistry, 2018

Boronic acids are proposed to be used as molecular inks. This allows chemical modification of the surface of polyvinyl alcohol (PVA) and PVA-related materials with boronic acid-containing molecules through boronate esterification using marker pen applicators. The resulting materials exhibit ...

A Multinuclear NMR Perspective on the Complexation between Bisboronic acids and Bisbenzoxaboroles with cis-Diols

24-Jan-2018 | Adele Larcher; Aurélien Lebrun; Mike Smietana; Danielle Laurencin, New Journal of Chemistry, 2018

The interaction between boronic acids and cis-diols is an intense area of research, with numerous applications in sensing, separation, drug delivery, and materials science. Several analytical tools have been proposed over the past 20 years to probe these interactions, but most of them are limited ...

An efficient and practical method for the enantioselective synthesis of tertiary trifluoromethyl carbinols.

12-Jan-2018 | Lorenzo G. Borrego, Rocío Recio, Manuel Alcarranza, Inmaculada Fernández, Noureddine Khiar, Advanced Synthesis & Catalysis, 2018

An efficient sulfinamide/olefin based chiral ligand, MetSulfolefin, has been developed for the enantioselective rhodium‐catalysed addition of aryl‐boronic acids to trifluoromethyl ketones. This shelf stable ligand is insensitive to air, oxygen and moisture, and it is obtained in only two high ...

A Nickel-Catalyzed anti-Carbometallative Cyclization of Alkyne-Azides With Organoboronic Acids: Synthesis of 2,3-Diarylquinolines

30-Dec-2017 | Ranjith Kumar Gadi; Ravi Kumar; Rajesh Manda; Sridhar Reddy Maddi, Chemical Communication, 2017

An anti-carbonickelative cyclization via reversible alkenylnickel E/Z isomerization of 2-azido phenyl propargyl alcohols with aryl boronic acids is achieved using Ni(acac)2 as the catalyst to access 2,3-diaryl quinolines. It represents a rare example of trapping the vinyl metal intermediate with ...

Copper Catalyzed S‐arylation starting from Aryl Boronic Acids and Tetraalkylthiuram Disulfide

21-Dec-2017 | Zhi-Bing Dong, Wan Xu, Fan Gao, European Journal of Organic Chemistry, 2017

A convenient and useful protocol for the synthesis of diverse S‐aryl dithiocarbamates was studied. Starting from aryl boronic acid and tetraalkylthiuram disulfide, the C‐S coupling proceeds smoothly catalyzed by copper, giving the desired S‐aryl dithiocarbamates in good to excellent yield. The ...
