Rylation reactions between 7-azaindole and 1,3- or 1,4-diodobenzene.The compounds 1e, 1i, 1j, 2k and 2l have been unambiguously identified by X-ray diffraction (Figure 2). PF-05105679 manufacturer Because of steric hindrance, their two or 3 rings have not been shown to become coplanar. Even though the torsion angles had been at most 25 inside the case of 1e (25.1 ), 1i (two.3/10.9 ),Molecules 2021, 26, x FOR PEER REVIEW5 ofMolecules 2021, 26,5 ofThe compounds 1e, 1i, 1j, 2k and 2l had been unambiguously identified by X-ray diffraction (Figure two). Resulting from steric hindrance, their two or 3 rings haven’t been shown to be coplanar. When the torsion angles were at most 25in the case of 1e (25.1, 1i 1j (14.2 ) and 2l (25.0and 2l (25.0and 25.0,worth was observedobserved for2k (22.7and (two.3/10.9, 1j (14.two and 25.0 ), a higher a higher value was for 2k (22.7 and 35.8 ). This could explain explain why decrease yields were noticed for 2k in comparison with 2l. 35.eight. This could why decrease yields were noticed for 2k in comparison to 2l.Figure 2.
