Fluorinated diazo diketones in rhodium(II)-catalyzed reactions with sultams: Chemoselective O-functionalization of amide carbonyl groups

Rhodium(II)-catalyzed decomposition of fluorinated diazo diketones in the presence of isothiazole-3(2H)-one 1,1-dioxides offers a chemoselective and useful tool for O-functionalization of their C=O groups by interaction with transient fluorine-containing Rh-II-diketocarbenoids. The resulting O-alkylimidates of isothiazole 1,1-dioxides, bearing (trifluoromethyl)acetyl groups, easily react with traces of H2O giving rise to stable hydrates of the perfluoroacetyl groups. No O -> N isomerization of O-alkylimidates (similar to the Lander-Chapman rearrangement) was observed under the reaction conditions studied.

Arsoles, stiboles, and bismoles

The developments in the synthesis of the five-membered heterocycles with one pnictogen (As, Sb, Bi) heteroatom have in the last 15 years or so been practically focused only on three types of compounds: saturated or unsaturated pnictogenoles, monofused pnictogenoles, and diffused pnictogenoles, where the fused ring is benzene, thiophene, isothiazole, benzothiophene, or benzofuran. Trendy is preparation and tuning of the optoelectronic properties of the target compounds, their complexes or polymers, respectively. Almost all syntheses of nearly all systems are based on transmetallation of lithium (for 1,3-diene known as Ashe’s method), potassium, Grignard, copper, titanium, or zirconium species (Fagan-Nugent zirconium metallacycle-transfer method), regardless of whether the system is saturated (as is the case for the majority of compounds) or unsaturated.
