A new approach for the synthesis of low valent metal sandwich complexes showing the unanticipated ease with which silylamides can function as leaving groups resulting in a 1D polymer of the repeating unit, [K(18-crown-6)][Cr2(C10H8)2], has been described.

AbstractObjective:We report a new approach to benign parapharyngeal space tumours: a single, subcondylar mandibular osteotomy.Method:Case report and review of the world literature concerning parapharyngeal space access and the various types of mandibular osteotomy.Results:The use of a single, subcondylar mandibular osteotomy achieves good exposure and satisfactory aesthetic and functional results, using a simple, easily performed technique that is fast and has minimal morbidity. In addition, this technique preserves the submandibular gland and avoids lip-splitting and post-operative intermaxillary fixation.Conclusion:To our knowledge, this is the first report of this approach to the parapharyngeal space. We propose this approach as the first choice for resection of benign neoplasms of the parapharyngeal space.

A new approach was designed for the synthesis of C6-substituted 2-triazolylpurine derivatives. A series of substituted products was obtained in SNAr reactions between 2,6-bistriazolylpurine derivatives and O- and C-nucleophiles under mild conditions. The products were isolated in yields up to 87%. The developed C–O and C–C bond forming reactions clearly show the ability of the 1,2,3-triazolyl ring at the C6 position of purine to act as leaving group.
