Pyrromethene-BF, complexes (P-BF,) 7 were obtained from a-uns,ubstituted pyrroles 5 by acylation and condensation to give intermediate pyrromethene hydrohalides 6 followed by treatment with boron trifluoride etherate. Conversion of ethyl cu-pyrrolecarboxylates 4 to a-unsubstituted pyrroles 5 was bro
