Competitive formation of η¹-1-phosphaallene and 1H-phosphirene complexes

Abstract

The 2H-azaphosphirene complex 1 reacts with triorganostannyl(ethoxy)acetylenes 2a,b to yield bifunctional η¹-1-phosphaallene 5a,b and 1H-phosphirene complexes 6a,b; 5a,b and 6a,b are characterized by NMR spectroscopy (¹³C, ³¹P) and complex 6b by single crystal X-ray diffraction.
