Lewis acid enhanced switching of the 1,1-dicyanodihydroazulene/vinylheptafulvene photo/thermoswitch.
نویسندگان
چکیده
Mild Lewis acids enhance the rate of the thermal conversion of vinylheptafulvene (VHF) to dihydroazulene (DHA). In the absence of light, stronger Lewis acids promote the otherwise photoinduced DHA to VHF conversion.

On the bromination of the dihydroazulene/vinylheptafulvene photo-/thermoswitch
BACKGROUND The dihydroazulene (DHA)/vinylheptafulvene (VHF) system (with two cyano groups at C1) functions as a photo-/thermoswitch. Direct ionic bromination of DHA has previously furnished a regioselective route to a 7,8-dibromide, which by elimination was converted to a 7-bromo-substituted DHA. This compound has served as a central building block for functionalization of the DHA by palladium-...
متن کاملChemoselective Synthesis of 1,1-diacetate Using Ni2+@ Hydroxyapatite-core@shell γ-Fe2O3 Nanoparticles as an Efficient and Reusable Lewis Acid Catalyst under Solvent Free Conditions
A simple and efficient method for the chemoselective 1,1-diacetate protection of aromatic aldehydes with acetic anhydride by using Ni2+ supported on hydroxyapatite-core-shell magnetic γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ni2+) under solvent free conditions. This method has several advantages, including high yield, short reaction time, simple work-up and recyclable property of the catalyst. The ca...
متن کاملSingle-molecule detection of dihydroazulene photo-thermal reaction using break junction technique
Charge transport by tunnelling is one of the most ubiquitous elementary processes in nature. Small structural changes in a molecular junction can lead to significant difference in the single-molecule electronic properties, offering a tremendous opportunity to examine a reaction on the single-molecule scale by monitoring the conductance changes. Here, we explore the potential of the single-molec...
متن کامل1,1-Alkenylboration of diarylphosphino-enynes: convenient synthetic entry to vicinal P/B Lewis pairs at extended conjugated π-frameworks.
Alkenylboranes R-CH=CH-B(C6F5)2 undergo carbon-carbon coupling by means of 1,1-alkenylboration with diarylphosphino-enynes to give substituted conjugated hexatriene derivatives that bear a vicinal pair of B(C6F5)2 Lewis acid and PAr2 Lewis base functionalities at their central carbon portions. A series of six examples was prepared and all compounds were characterized by X-ray diffraction. Conse...
