3. The alcohol and amine donors in fac-Cr(CO)3(κ3-S-PNO) were substituted upon addition of trivinylphosphine to 1 to give the complex fac-Cr(CO)3(κ1-P-S-PNO)P(C2H3)3}2, 4. Addition of base to 4 gave a coordinated linear tridentate P3 ligand through the formation of two new chelate rings via hydrophosphination of one vinyl group on each coordinated P(C2H3)3 with the P–H bonds of the complexed S-PNO
