Abstract

The diphosphines m-C6H4 (CH2Pt-Bu2) 21 and m-C6H4 (CH2PCy2) 22 were prepared and oxidized with Me3SiN3 to m-C6H4 (CH2 (t-Bu2) PNSiMe3) 23 and m-C6H4 (CH2 (Cy2) PNSiMe3) 24, and subsequently converted to m-C6H4 (CH2 (t-Bu) 2PNH) 25 and m-C6H4 (CH2 (Cy) 2PNH) 26. Reaction of 5 and 6 with Ti (NMe2) 4 afforded the yellow compounds m-C6H4 (CH2 (t-Bu) 2PN) 2Ti (NMe2) 27 and m-C6H4 (CH2 (Cy) 2PN) 2Ti (NMe2) 28, ...
