A Straightforward Synthesis of 5‐Methylaaptamine from Eugenol, Employing a 6π‐Electrocyclization Reaction of a 1‐Azatriene

“…The longest Ru–Ru bond length [Ru1–Ru3 = 2.8930(6) Å] is cis to the monodentate AsPh 3 ligands, while the bridged Ru–Ru distance [Ru1–Ru2 = 2.8461(7) Å] is slightly shorter than the unbridged Ru2–Ru3 bond [2.8495(7) Å]. Similar observations were also made in Ru 3 (CO) 9 (dppm)AsR 3 ,12 Ru 3 (CO) 9 (dppm)P R 3 [ R = Ph, Cy, i Pr, (Et),14 Ru 3 (CO) 9 (dppm)(dppa),18 and Ru 3 (CO) 9 (dppm)P(C 4 H 3 S) 3 19]. Koutsantonis and co‐workers remarked that the longest Ru–Ru bond cis to monodentate P ligands is correlated with the size of the ligand 14.…”

“…The effectiveness of group 15 monodentate ligands in coordinating to the central metal atoms has been attributed to the versatility of their electronic and steric properties 9–11. Previously, we have reported the crystal structures of the series of trisubstituted complexes Ru 3 (CO) 9 (dppm)AsR 3 12 and Ru 3 (CO) 9 (dpam)PR 3 13 by using the thermal method, which enabled us to make comparisons with regards to the molecular geometric structure and reactivity.…”

“…A large number of substituted derivatives of the type Ru 3 (CO) 12-n L n (L = group 15 ligand) have been reported (Bruce et al, 1985(Bruce et al, , 1988a. As part of our study on the substitution of transition metal-carbonyl clusters with mixed-ligand complexes, we have published several structures of triangulo-triruthenium-carbonyl clusters containing mixed P/As and P/Sb ligands (Shawkataly et al, 1998(Shawkataly et al, , 2004(Shawkataly et al, , 2010a). Herein we report the synthesis and structure of the title compound.…”
