Dinaphthosulfoxide has been synthesized, and confirmed by the experimental methods. The
geometrical optimization of the two isomers of the molecule in their ground state was studied …

In this research, some new eighteen‐membered‐ring nitrogen‐pivot lariat ethers were
synthesized from a tri‐aza macrocyclic diamide containing dibenzosulfide and a coumarin …

New dinaphthosulfoxide aza crowns were prepared from the corresponding
dinaphthosulfoxide diester and diamines under reflux conditions (conventional heating) and …

Six new aza crown ethers (4–9) were synthesized based on the conventional route crab‐like
method with the reaction of corresponding bis‐α‐chloroacetamidediphenylsulfide …

Some new aza thia crowns were prepared. A new diester was first prepared from the
reaction of α, α′-bis (bromomethyl) benzene and methylthioglycolate. Aza crowns were …

Four new thia-and four new aza-crown ethers were synthesized using the reaction of
ethylene glycols ditosylated with 1, 1-(2, 2-dihydroxynaphthyl) sulfide (DNS) and 2, 6-bis (3 …

In this research work, dinaphthyl sulfide diester was prepared from the reaction of 1, 1′‐
thiobis (2‐hydroxy naphthalene) and methylchloroacetate. Its aza‐macrocyclic derivative …

In this study, hierarchical H-ZSM-5 zeolite is prepared via post-synthetic modification of
parent H-ZSM-5 zeolite (Si/Al= 35) synthesized from bagasse (BGA) as silica source using …

In this research work, we report the synthesis of macrocyclic diamides from the reaction of
diesters and aliphatic diamines in the presence of caesium carbonate. It has been …

New aza thia crowns were prepared from the reaction of 2, 2′-diaminodiphenyl disulfide
and diacids or diacid chlorides. Diacids are malonic acid, adipic acid, sebacic acid, and 2 …
