{2,7-Dimethoxy-8-[4-(propan-2-yloxy)benzoyl]naphthalen-1-yl}[4-(propan-2-yloxy)phenyl]methanone

Abstract: The title compound, C32H32O6, crystallized with two independent molecules in the asymmetric unit. Each molecule has essentially the same feature of non-coplanar aromatic rings whereby the two 4-isopropoxybenzoyl groups are twisted in a perpendicular manner to the naphthalene ring and oriented in the same direction (syn-orientation). The benzene rings of the aroyl groups make dihedral angles of 16.13 (7) and 25.31 (7)° in the two molecules. These benzene rings make dihedral angles of 88.38 (8) and 75.32 (7)° wi… Show more

“…According to the authors′ knowledge, most 1,8-diaroylnaphthalene derivatives have anti-oriented structures. Recently, we have also clarified another structure of the 1,8-diaroylnaphthalene derivatives, where the two aroyl groups are situated in same direction (syn-orientation), 2,7-dimethoxy-1,8-bis(4-phenoxybenzoyl)naphthalene (Hijikata et al, 2010) and 1,8-bis(4-isopropoxybenzoyl)-2,7-dimethoxynaphthalene [{2,7-dimethoxy-8-[4-(propan-2-yloxy)-benzoyl]naphthalen-1-yl}[4-(propan-2-yloxy)phenyl]methanone] (Sasagawa, Takeuchi et al, 2013). As a part of our ongoing studies on the molecular structures of these kinds of homologous molecules, the X-ray crystal structure of the title compound, 1,8-diaroylated naphthalene bearing ethoxy groups on the aroyl moieties, is discussed herein.…”

“…17,18 Molecular structures of 1,8-diaroylated 2,7-dialkoxynaphthalene compounds in crystals have common features that two aroyl groups are noncoplanarly located to the 2,7-dialkoxynaphthalene core and oriented in an opposite direction 19 with a few exceptional compounds bearing unidirectional-alignment of aroyl groups. [20][21][22] The molecular packing of 1,8-diaroylated 2,7-dialkoxynaphthalene compounds are mainly stabilized by weak hydrogen bonds. Four kinds of noncovalent-bonding interactions, (sp 2 )C-H···O=C hydrogen bond, (sp of frequency.…”
