✦ Synopsis

The tetrakis(phosphane oxide) C 6 H 2 {CH 2 P(O)Ph 2 } 4 -1,2,4,5 (5), has been prepared in high yield from the Arbuzov reaction of C 6 H 2 (CH 2 Br) 4 -1,2,4,5 (4), with excess (7 equiv.) of Ph 2 POEt. Subsequent reduction of 5 with HSiCl 3 (12 equiv.) in C 6 H 4 Cl 2 -1,2 afforded the new tetraphosphane C 6 H 2 (CH 2 PPh 2 ) 4 -1,2,4,5 (6), in high yield. The reaction of 6
