The pyrrolidine-2,5-dione ring in the title compound, C(15)H(15)NO(6), is in a twisted conformation with the acetyl C atoms projecting to opposite sides of the ring. The acetyl groups lie to opposite sides of the five-membered ring. The benzene ring is roughly perpendicular to the heterocyclic ring, forming a dihedral angle of 76.57 (14)° with it. In the crystal, mol-ecules are connected throug...

This paper compares the dyeing of cellulose diacetate (cellulose-based) and polyester fabrics using supercritical carbon dioxide (SC-CO2) aqueous media. The benefits in SC-CO2 were clearly demonstrated lab-based pilot-scale studies terms increased colour strength, uniformity, fastness absence auxiliaries such as dispersing agents or surfactants. In addition, “super-levelling” nature medium was ...

Bioplastics are increasingly replacing traditional plastics in many sectors, but the legislative and operative frameworks for their disposal remain unclear: they should be collected treated together with organic fraction of municipal solid waste (OFMSW), often do not biodegrade satisfactorily plants that treat OFMSW. This work focuses on a type cellulose diacetate employed eyewear industry to a...

One of the hypervalent iodines most widely used as an oxidizing agent in organic chemistry is (diacetoxyiodo)benzene (PhI(OAc)2), also known (DAIB), phenyliodine(III) diacetate (PIDA). In this septennial mini-review, authors have concisely and systematically presented representative applications PIDA synthesis involving C-H functionalization, hetero-hetero bond formations, heterocyclic ring con...

The two naphthyl fused-ring systems in the title compound, C(22)H(26)O(6), are aligned at 86.7 (1)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

In the title compound, C(20)H(22)O(6), the mean planes through the benzene rings make a dihedral angle of 59.82 (7)° with each other. Weak inter-molecular C-H⋯O inter-actions together with π-π stacking inter-actions [centroid-centroid distance = 3.830 (1) Å] between benzene rings are observed in the crystal packing.

Catechols were synthesized from safrole. Nine derivatives were prepared and assessed for antiproliferative effects using different human cell lines. The in vitro growth inhibition assay was based on the sulphorhodamine dye to quantify cell viability. The derivatives 4-allylbenzene-1,2-diol (3), 4 4-[3-(acetyloxy)propyl]-1,2-phenylene diacetate (6) and 4-[3-(acetyloxy)propyl]-5-nitro-1,2-phenyle...
