Photoelectrochemical cross-dehydrogenative coupling of benzothiazoles with strong aliphatic C-H bonds

A photoelectrochemical strategy for the cross-dehydrogenative coupling of unactivated aliphatic hydrogen donors (e.g.alkanes) with benzothiazoles is reported. We used tetrabutylammonium decatungstate as the photocatalyst to activate strong C(sp3)-H bonds in the chosen substrates, while electrochemistry scavenged the extra electrons.

Introduction of Heteroaromatic Bases onto Cycloalkanes with BPO

Heteroaromatic bases, such as lepidine, phenanthridine, isoquinoline, etc., were treated with cycloalkanes, such as cyclopentane, cyclohexane, cycloheptane, cyclooctane, etc., under warming conditions with benzoyl peroxide (BPO) to form heteroaromatic bases bearing cycloalkyl groups in good yields. Here, the inert C(sp3)-H bond of cycloalkanes could be functionalized to C(sp3)-heteroaromatic bases via an oxidative radical reaction pathway under transition-metal-free conditions.

Ni-Catalyzed Reductive Liebeskind-Srogl Alkylation of Heterocycles

Herein we present a Ni-catalyzed alkylation of C-SMe with alkyl bromides for the decoration of heterocyclic frameworks. The protocol, reminiscent to the Liebeskind-Srogl coupling, makes use of simple C(sp2)-SMe to be engaged in a reductive coupling. The reaction is suitable for a preponderance of highly valuable heterocyclic motifs. In addition to cyclic bromides, noncyclic alkyl bromides are well accommodated with exquisite levels of retention over isomerization. The protocol is scalable and permits orthogonal couplings in the presence of other functionalization handles.
