Advanced Materials Interfaces, EarlyView.This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...

Hydrotelluration of alkynes: a unique route to Z-vinyl organometallics
Journal of the Brazilian Chemical Society, 2001 The hydrotelluration reaction of alkynes is reviewed. The transformation of vinylic tellurides into reactive vinyl organometallics and the coupling reactions of vinylic tellurides with alkynes and organometallics are presented.

Electrocatalytic regio- and stereoselective carboxylation of terminal alkynes with CO2
Green Synthesis and CatalysisCarboxylation with CO2 is a practical and streamlined way to construct a variety of sophisticated carboxylic acids and their derivatives. However, a series of elegant methods focus mainly on C(sp3)– and C(sp2)– carboxylation and involve transition-metal ...

Glycerol as Precursor of Organoselanyl and Organotellanyl Alkynes
Molecules, 2017 Herein we describe the synthesis of organoselanyl and organotellanyl alkynes by the addition of lithium alkynylchalcogenolate (Se and Te) to tosyl solketal, easily obtained from glycerol.

Advanced Materials Interfaces, EarlyView.The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.

Recent advances in carbocupration of α-heterosubstituted alkynes
Beilstein Journal of Organic Chemistry, 2010 Carbocupration of α-heterosubstituted alkynes leads to the formation of stereodefined functionalized vinyl copper species as single isomer. Recent advances in the field show that a simple pre-association of the organometallic derivative with an ...

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection
Advanced Materials Interfaces, EarlyView.A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...

[3 + 2]-Cycloaddition reaction of sydnones with alkynes
Beilstein Journal of Organic Chemistry, 2018 This review covers all known examples of [3 + 2]-cycloaddition between sydnones and both terminal as well as internal alkynes/cycloalkynes taken from literature since its discovery by Huisgen in 1962 up to the current date.

A stereo- and regioselective Mn(I)-catalyzed hydroboration of terminal alkynes with pinacolborane (HBPin) is described. The hydroboration reaction is highly Z-selective in the case of aryl alkynes and E-selective in the case of aliphatic alkynes.
