Design and synthesis of a new series of tetra(polycyclic aryl)ethenes: Achieving aggregation-induced emission and efficient solid-state photoluminescence

Abstract Three novel ethene derivatives substituted by four polycyclic aromatic hydrocarbons, tetrakis(4,5,9,10-tetrahydropyren-2-yl)ethene, tetra(fluoren-2-yl)ethene and tetra(biphenyl-4-yl)ethene, were efficiently synthesized and characterized by NMR sp

Synthesis of fluorenone derivatives through Pd-catalyzed dehydrogenative cyclization

Palladium-catalyzed dual C-H functionalization of benzophenones to form fluorenones by oxidative dehydrogenative cyclization is reported. This method provides a concise and effective route toward the synthesis of fluorenone derivatives, which shows outstanding functional group compatibility.

Hydroxylation of phenolic compounds

Phenolic compounds, e.g., phenol, are hydroxylated, preponderantly into the para-isomer, e.g., hydroquinone, by reaction with hydrogen peroxide in the presence of an effective amount of a strong acid and a catalytically effective amount of a keto compound having the formula (II): STR1 in which R1 and R2, which may be identical or different, are each a hydrogen atom or an electron-donating group; n1 and n2, which may be identical or different, are numbers equal to 0, 1, 2 or 3, with the proviso that the two carbon atoms located at the α-position with respect to the two carbon atoms bearing the --CO group may be bonded together via a valence bond or via a --CH2 -- group, thereby forming a keto-containing ring member which may either be saturated or unsaturated.
