1st International Conference in: Hypervalent Iodine

The ever expanding use of hypervalent iodine reagents in organic synthesis has made it imperative that workers involved in the field should come together. Such a gathering will give them the op-portunity, apart from the presentation of their latest results, for exchange of ideas, lively discussions about topics of mutual interest and hopefully the initiation of future collaborations. We are very happy that the 1st International Conference on Hypervalent Iodine is at last realized, with the participation of many distinguished chemists from Europe, the USA and Japan. We do hope that our expectations will be fullfilled and there will be many more conferences on the subject in the years to come. We should like to thank most sincerely the following:

1. The Chemistry Department of the University of Thessaloniki which put under its aegis the Con-ference
2. The Senate of the University of Thessaloniki for financial assistance
