The creation of electronically excited species by the 193 nm excimer laser photolysis of PC& and PBr, has been studied. In addition to halogen and phosphorus atomic lines, emission is detected from highly excited states of Cl2 and Br2, respectively, formed by a two-photon process. We also observe pr

## Abstract Phosphorylation of __N__โ€trimethylsilylโ€ and __N__โ€dimethylโ€tertโ€butylsilylpyrroles with phosphorus tribromide in pyridine proceeds selectively at position 3 of the pyrrole ring. Removal of the trialkylsilyl protecting group has furnished the first representatives of __N__โ€unsubstituted
