Abstract:

The following titaniumIV phosphinates were prepared, mainly by metathesis i TiOR2OPRRO2 with R, R, and R, respectively, CH3, CH3, or C4H9 CH3, C6H5, and C2H5 or C6H5, C6H5, and C2H5 or i-C3H7 ii TiCl2OPC6H52O2 iii TiOOPRRO2 with R and R both CH3, both C6H5, or one CH3 and one C6H5 iv TiOPC6H52O4 and v TiBB OPRRO2 with BB, R, and R, respectively, ortho-OPhO, CH3 or C6H5, and C6H5 ortho-OPhCO2, CH3, and C6H5 CH32CO-CH2CHO-CH3, C6H5, and C6H5 OC3H6O, CH3 or C6H5, and C6H5 PO2CH2PO2C6H5, CH3, and C6H5. TiCl2OPC6H52O2 was prepared by the thermal decomposition of TiCl4OPC6H52OC2H52. Molecular weight data show that all the titaniumIV phosphinates made are at least trimers, and that some have degrees of polymerization exceeding 20. Their infrared spectra are consistent with phosphinate bridging, and it is probable that double phosphinate bridges are present in most of the polymers. Infrared data also are in accord with TiO analysis shows that weight loss starts at temperatures as high as 450 deg in nitrogen for some of the polymers prepared. Author
