More than 3.26 billion Internet users are using Web and mobile applications every day for retail services and businesses processing; information management and retrievals; media and social interactions; gaming and entertainments, etc. With the rapid growth in simultaneous users and data volume, such applications often rely on distributed databases to handle large magnitudes of On-Line Transacti...

[Bis(trifluoroacetoxy)iodo]benzene (BTI) and (diacetoxyiodo)benzene (DIB) efficiently promote the formation of acylnitroso species from hydroxamic acids in the presence of various dienes to give the corresponding hetero-Diels-Alder (HDA) adducts in moderate to high yields. The present method could be applied to the HDA reactions of acylnitroso species with o-benzoquinones generated by the oxida...

1-Carbamoyl-2-oxopropyl acetate derivatives were synthesized through an acetoxylation process to methylene with the aid of (diacetoxyiodo)benzene (DIB) as the oxidant. Not only mild reaction conditions, but also excellent yields and good substrate scope make the present protocol potentially useful in organic synthesis.

Recently a new process for the synthesis of the commercially important semi-crystalline, engineering thermoplastic poly(p-phenylene sulfide/disulfide), PPS/DS, was presented [1]. This process, based on the reaction of p-diiodobenzene (DIB) and sulfur at elevated temperatures (Figure 1), generates a polymeric material containing para-substituted aromatic groups connected by sulfide and disulfide...
