Long-Range Self-Assembly of an Electron-Deficient Hexaazatrinaphthylene with Out-of-Plane Substituents

The unprecedented time-dependent long-range supramol-ecular assembly of electron-deficient hexaazatrinaphthylene (HATN) core based on peripheral crowding with three out-of-plane cyclic ketals is reported. The single-crystal X-ray structure of the diethyl derivative provided detailed information as to how four molecules in a repeating unit were packed in order to avoid steric crowding of the out-of-plane cyclic ketal side chain, providing locking and fastening for stabilizing the self-assembled structure. The polarizing optical microscopy (POM) and differential scanning calorimetry (DSC) did not instantaneously show any phase transition upon the cooling process. To our surprise, POM images showed a nucleation of spherulite up to 100 μm after 24 hour later. X-ray diffraction data further confirmed that these soft crystal formed a hexagonal-like crystal. The long-range self-assembly of the new material showed a slight red shift in the UV-vis absorption spectra and further substantiated by computational method.

Synthesis of symmetrical ketones from Grignard reagents and 1,1′-carbonyldiimidazole

Coupling reactions of 1,1′-carbonyldiimidazole with Grignard reagents provide a rapid and straightforward method for the synthesis of symmetrical ketones. Georg Thieme Verlag Stuttgart.

The CoCl2/Ph(Et)2N:BH3/CO system: Reactions of the borane and cobalt carbonyl species

The CoCl2/Ph(Et)2N:BH3/CO system is useful for the hydroboration and carbonylation of alkenes to obtain the corresponding dialkyl ketones. The cobalt carbonyl species formed in situ in this way is also useful for hydroacylation-cyclisation of norbornene and for the Pauson-Khand reaction.

Synthesis of Dialkyl Ketones from Alkenes Using Ph(Et)2N:BH3/CoCl2/CO Reagent System

Reaction of alkenes with Ph(Et)2N:BH3/CoCl2/Co in THF followed by oxidation gives the corresponding dialkyl ketones.

ALDEHYDE AND KETONE SYNTHESES USING METHYLTHIOMETHYL p-TOLYL SULFONE

Methylthiomethyl p-tolyl sulfone (1) was conveniently alkylated to give mono- and dialkylated products (2 and 4).Reaction conditions for the transformation of 2 and 4 into aldehydes (3) and ketones (5), respectively, were exploited.

NOVEL CONVERSION OF A KETONE DIMETHYL DITHIOACETAL S,S-DIOXIDE TO THE CORRESPONDING KETONE AND ITS APPLICATION TO SYNTHESIS OF ACYCLIC AND CYCLIC KETONES

A ketone dimethyl dithioacetal S,S-dioxide was easily hydrolyzed with hydrochloric acid in refluxing methanol and this transformation was applied to a new method for making acyclic and cyclic ketones by the use of formaldehyde dimethyl dithioacetal S,S-dioxide.
