Its asymmetric unit comprises two crystallographically independent molecules (A and B) being the stereoisomers. Both molecules are linked by pairs of N-HÁ Á ÁO hydrogen bonds, forming a dimer with an R 2 2 (16) ring motif. The dimers are connected by further N-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds, forming chains along the c-axis directionÁC-BrÁ Á Á interactions between these chains contribute to the stabilization of the molecular packing. Hirshfeld surface analysis showed that the most important contributions to the crystal packing are from HÁ Á ÁH, CÁ Á ÁH/HÁ Á ÁC, OÁ Á ÁH/HÁ Á ÁO, BrÁ Á ÁH/HÁ Á ÁBr and NÁ Á ÁH/HÁ Á ÁN interactions.

Sequential treatment of the amides with Tf2O/2-chloropyridine and copper trimethylsilylacetylide gives access to C-silyl alkynyl imines as precursors for the cycloisomerization. This ruthenium-catalyzed step can be directly performed with the silylacetylides which are desilylated in situ. Only in two cases, the in situ desilylation is found to be exceedingly slow, and terminal alkyne substrates (V) and (XVI) are isolated prior the cyclization (to be continued).-(MOVASSAGHI*, M.;

When ethylenediamine was used as the amine component of the reaction, dihydro-and tetrahydroimidazopyridines were selectively obtained in good to high yields. On the other hand, the use of benzylamine led to the formation of 2-imino-1,2-dihydropyridine products. The reactions were found to tolerate the presence of electron-donating and withdrawing substituents on the benzylidenemalononitrile reactants. Products of these reactions are crystalline and can be isolated by a simple procedure at room temperature in good yields and with high purity.

In the crystal, the phenol group forms a hydrogen bond to the hydroxy O atom belonging to the alkyl substituent of an adjacent molecule, forming a chain along the ac diagonal. The Cl atom is disordered over two positions in a 0.73 (4):0.27 (4) ratio.
