• Description: Barium manganate (chemical formula BaMnO4) is a type of manganates in which the manganese is in a +6 oxidation state. It is obtained by heating manganese dioxide with barium carbonate or nitrate, or by precipitating potassium manganate with barium chloride.1 Barium manganate gives a green pigment, which was used to make manganese blue. Barium manganate can be used in the oxidation of a variety of functional groups efficiently and selectively: alcohols to carbonyls, alcohols to aldehydes, diols to lactones, thiols to disulfides, aromatic amines to azo-compounds, hydroquinone to p-benzoquinone, benzylamine to benzaldehyde, etc. 2,3
• Uses: As pigment in fresco painting instead of Scheele's green because not so poisonous as latter. As mild oxidizing agent in organic synthesis. Useful for the selective oxidation of diols.

Tetraacylethenes as dienophiles and hetero dienes in two-step Diels- Alder reactions

10.1002/(SICI)1099-0690(199912)1999:12<3343::AID-EJOC3343>3.0.CO;2-S

The research explores the synthesis and reactivity of tetraacylethenes, specifically tetraacetylethylene (7a) and diacetyldibenzoylethylene (7b), in Diels–Alder reactions. The study aims to provide a novel access to functionalized [4.3.3]propellanes and clarify conflicting reports on the oxidative coupling of benzoylacetone (15b). The researchers found that tetraacetylethylene (7a) behaves as a mechanistic chameleon, yielding two different Diels–Alder products with 1,2-dimethylenecyclohexane, and can react as both an electron-deficient dienophile and a 1-oxa-1,3-diene. Key chemicals used in the process include barium manganate, iodosobenzene, 1,2-dimethylenecyclohexane, and various derivatives of benzoylacetone. The conclusions drawn from the study are that tetraacetylethylene (7a) is a versatile reactant in Diels–Alder reactions, capable of forming different products depending on the reaction conditions, and that the reactions likely proceed via a zwitterionic intermediate, offering insights into the ambiguity observed in the Diels–Alder chemistry of such compounds.
