A direct cyanation of terminal alkynes for the synthesis of propionitrile derivatives, with the aid of silver salt using water additive, has been achieved. The cyano source used is N-isocyanoiminotriphenylphosphorane, which is nontoxic, safe, and easy to handle. This protocol is characterized by its operational simplicity, high efficiency with excellent yields, broad substrate scope, and greater functional group tolerance.

A new synthesis of 3-amino-5-arylisothiazoles is reported. The reaction is operationally simple, utilises readily synthesised propynenitriles as starting materials and is tolerant of a range of functional groups. The optimised reaction conditions can also be used with 3-chloropropenenitriles in place of propynenitriles. (C) 2018 Elsevier Ltd. All rights reserved.

An efficient synthesis of 3-halo-3-arylacrylonitrile is described from the direct addition between cyanoalkynes and inorganic alkaline metal halides such as LiCl, LiBr and KI in good to satisfactory yields. No transition metal is needed for the synthesis of iodo- and bromo-products, although Pd catalyst is used to accelerate the chloro-product.
Norbornadiene‐quadricyclane (NBD‐QC) photoswitches are candidates for applications in solar thermal energystorage. Functionally, they rely on an intramolecular [2+2] cycloaddition reaction, which couples the S0 landscape on the NBD side to the S1 landscape on the QC side of the reaction and vice‐versa. This commonly results in an unfavourable correlation between the first absorption maximum and the
