Photochemical Irradiation of R₃SiH in the Presence of [(η⁵-C₅H₅)Fe(CO)₂CH₃] in DMF Leads to Disiloxanes not Disilanes

Not SiSi, rather SiOSi: Dimethylformamide (DMF) acts as an oxygen source in the efficient transformation of tertiary silanes (R3SiH; R3=Ph2Me, PhMe2, Et3) into disiloxanes R3SiOSiR3 in the presence of the catalyst [(η5‐C5H5)Fe(CO)2CH3] (1; see scheme). This result contradicts a recently publish...

Summary:Not SiSi, rather SiOSi: Dimethylformamide (DMF) acts as an oxygen source in the efficient transformation of tertiary silanes (R3SiH; R3=Ph2Me, PhMe2, Et3) into disiloxanes R3SiOSiR3 in the presence of the catalyst [(η5‐C5H5)Fe(CO)2CH3] (1; see scheme). This result contradicts a recently published related study, in which the formation of disilanes is reported.
