Reaction of Phenylurea and N-Trimethylsilyl-N'-phenylurea with Vanadocene and N-Bromosuccinimide
摘要:
Phenylurea and N-trimethylsilyl-N'-phenylurea react with vanadocene (Cp2V) in toluene to,give N-(eta(5)-cyclopentadienyl)vanadio-N'-phenylurea as a major product and Cp2VN=C=O and aniline as by-products. The reaction of N-trimethylsilyl-N'-phenylurea with N-bromosuccinimide in THF produces, instead of expected N-phenylureidosuccinimide and bromotrimethylsilane, succinimide and N-(p-bromophenyl)-N-trimethylsilylurea which hydrolyzes to form (p-bromophenyl)urea.
