## Abstract A successive N → C~2~ → C~3~ migration of the dichlorophosphino group has been found to occur in phosphorylation of unsubstituted pyrrole with phosphorus trichloride. As a result of this migration, a number of hitherto unknown C‐phosphorylated N‐unsubstituted pyrroles have been obtained
## Abstract A N → C~3~ migration of the dichlorophosphino group has been revealed in the phosphorylation of unsubstituted indole with phosphorus trichloride. Several 3‐phosphorylated NH‐indole derivatives have thus been obtained and N‐acylation of one of the products has been performed. © 2009 Wile

The phosphorylation of N-methylpyrrole with phosphorus (III) halides has been studied. Migration of the dibromophosphino group from the second to the third position of N-methylpyrrole, leading to the 3-dibromophosphine, has been found. Methods for the synthesis of 2,4-bisphosphorylated pyrroles have
