Abstract:	Phenylurea and N-trimethylsilyl-N'-phenylurea react with vanadocene (Cp₂V) in toluene to give N-(⁵-cyclopentadienyl)vanadio-N'-phenylurea as a major product and Cp₂VN = C = O and aniline as byproducts. 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.
