Functionalized benzylic manganese chlorides were smoothly prepared by the direct insertion of magnesium into benzylic chlorides in the presence of MnCl2·2LiCl. Reactions with acid chlorides, aldehydes, an allyl bromide, and an enone proceed without any additional transition metal.

The synthesis, antileukemic and antiplatelet activity evaluation of 2,3-diaryl-6,7-dihydro-5H-1,4-diazepines are described. In general, it was found that compound 17o showed moderate antileukemic activity against MOLT3 human leukemic cancer cell lines. An arachidonic acid induced platelet aggregation effect on washed rat platelets was studied. Compound 17i was found to be the most potent. The antiplatelet properties may be mediated by interference with the arachidonic acid pathway.

Selenium dioxide oxidation of 1,2-diarylethanones to corresponding diones by conventional method takes upto 8 hr. The same oxidation under microwave radiations using dimethylsulfoxide as solvent reduces the reaction time considerably (30 to 90 sec). The method reported is efficient and time saving.
Synthesis of novel substituted diaryl-1,4-diazepines

, p. 901 - 906 (2008/02/12)
In this paper a convenient route to new 2,3-diaryl-substituted 1,4-diazepines is described through cyclization of ethanedione derivatives and 1,3-propanediamine. The ethanedione derivatives required were synthesized by microwave-assisted oxidation from ethanones.
