Thermal ring opening of [2-(bis(trimethylsilyl)methyl)-3-phenyl-2H-azaphosphirene-κP]pentacarbonylchromium(0), -molybdenum(0), or -tungsten(0) (1a−c) in the presence of three different alkynes, phenylacetylene, ethyl acetylenecarboxylate (EAC), and dimethyl acetylenedicarboxylate (DMAD) (i−iii), was investigated, using toluene (a) and benzonitrile (b) as solvents, whereby special emphasis was to determine
