Organothiometallate addition reactions with electronegative alkynes. The X-ray molecular structures of [(η5-C5H5)(CO)FeC(O)C(CF3)
CHSMe], [(η5-C5H5)(CO)FeC(CF3)
CHS(Me)Fe(CO)(η5-C5H5)SMe], and [(η5-C5H5)(CO)MoC(O)C(CF3)C(CF3)C(O)SMe]
Abstract
Addition of F3CCCH and F3CC
CCF3 to [(η5-C5H5)FeSMe(CO)2] gives mono- and bi-nuclear methylthio-alkenyl complexes, and with [(η5-C5H5)Mo(CO)3]2 and MeSSMe a novel six-membered metallocycle incorporating S-methyl thioester and η3-acryloyl functions is obtained.
