Transient [3,3] Cope rearrangement of 3,3-dicyano-1,5-dienes: computational analysis and 2-step synthesis of arylcycloheptanes.

A simple and modular route to arylcycloheptene scaffolds is reported. The two-step route from Knoevenagel adducts and allylic electrophiles is made possible through the design of a Cope rearrangement that utilizes a "traceless" activating group to promote an otherwise thermodynamically unfavorable transformation. Experimentally, the [3,3] rearrangement occurrs transiently at room temperature with a computed barrier of 19.5 kcal mol-1, which ultimately allows for three-component bis-allylation. Ring-closing metathesis delivers the arylcycloheptane and removes the activating group. This report describes the design and optimization of the methodology, scope and mechanistic studies, and computational analysis

Bis[1-(2-eth­oxy­phen­yl)-3-(4-nitro­phen­yl)triazenido]mercury(II)

In the title compound, [Hg(C14H13N4O3)2], the central Hg atom (site symmetry 2) is six-coordinated by two tridentate 1-(2-eth­oxy­phen­yl)-3-(4-nitro­phen­yl)triazenide ligands through two N and one O atoms. The mononuclear complex mol­ecules are connected into two parallel chains by inter­molecular C—H⋯O hydrogen-bonding inter­actions. These chains are connected to each other by face-to-edge C—H⋯π inter­actions between the CH of the ethoxy groups and the aromatic rings, resulting in a two-dimensional architecture in the ac plane

Vision Indicators for an Islamic University in Reference to the Qur'an and Hadith

Developing a vision and planning for bright futures in a way that will envisage growth and progress form the first and most fundamental step in designing the structure of any organization and institution. However, in spite of all efforts aimed at elevating the institution of university to the desired status of a university in our country, and in spite of all the concerns for Islamicizing universities as sacred institutions, the vision for a university whose values are based on Islamic teachings is not adequately developed yet. This paper therefore aims to have a look on general aspects of concepts of vision and Islamic university in order to determine the main characteristics of an Islamic university and the indicators for developing a vision for such a university. It also refers to the Qur’an verses and Islamic narrations from ahl ul-bayt [the fourteen Infallibles in the belief of Shi‘a] and makes inferences from these teachings to present an adequate vision for and a befitting picture of an Islamic university. This study introduces the Islamic university as an institution with five key aspects: academic identity, religious orientation, research capacity, efficiency for the society, and satisfaction-centeredness. It then develops an ideal vision for an Islamic University based on four indicators which, together, propose a model for an Islamic type of university. They include: knowledge, capability, goodness, and beauty
