Facile synthesis of C-phosphanylformamidines via a carbene pathway
摘要:
A direct synthetic approach to C-phosphanyl-N,N-dialkyl-N'-aryl(alkl)-formamidines was developed. It was shown that phosphorylation of the formamidines proceeds at the nitrogen atom affording N-phosphanylformamidinium salts. Upon deprotonation, these salts gave C-phosphanylformamidines via formation of carbenes followed by a 1,2-phosphorus shift. (C) 2013 Elsevier Ltd. All rights reserved.
