Abstract

The crystalline dilithium diphosphide [Li (tmeda)] 2 [C6H4 (PR) 2-1, 2] 1 [R= SiMe3, obtained from C6H4 (PRR ″) 2-1, 2 (R′= R ″= H or R, or R′= H and R ″= R)] reacts with H2O, SiCl3Me, or [Zr (η-C5H3R2-1, 3) 2Cl2] to yield rac-and meso-C6H4 (PHR) 2-1, 2, C6H4 (PR2) 2-1, 2, or [[graphic omitted] R) 2-1, 2}], respectively; whereas 1 with RR-Me2C (OĊHCH2OTs) 2 (Ts= toluene-p-sulfonate) or SiButCl3 affords C6H4 [[graphic omitted] H2 ...
