A simple, eco-friendly and convenient procedure has been developed for the synthesis of diphenyl diselinides from readily available aryl boronic acids by reaction with SeO2 in the presence of iodine under simple conditions. The methodology is reported about 19 examples and applicable to a broad scope of aryl boronic acids containing electron-rich and electron-poor substituents. Apart from being milder and environmentally benign conditions, this synthetic protocol comprises a novel, reliable methodology to give good to high yields of the desired diaryl diselenides.

The first ipso -selenocyanation of arylboronic acids is achieved using selenium dioxide and malononitrile under mild conditions. The reaction is successful even without metal or base in DMSO. The major advantages of this new method are an easy set-up, excellent yields, and the use of odorless and inexpensive selenium reagents. Basic conditions subsequently afford new access to diaryldiselenides in good yields without isolating the organoselenocyanate intermediates.
