The efficient synthesis of carbodiimides using a titanium imido complex
摘要:
An efficient it synthesis of carbodiimides or ureas from the combination of a titanium imido complex 2 and a range of 12 aryl and aliphatic isocyanates is described Control experiments suggest that carbodimide formation is via heterocumulene metathesis through a transient intermediate eta(2)-ureato-N O metallacycle 8 (C) 2010 Elsevier Ltd All rights reserved
