Fig. 24. (a) Top and (b) side views of the atomic structure of Si(l 1 l)lxl-As. The values of silicon-arsenic bond length R), silicon-arsenic-silicon bond angle and outward displacement of the As atom from the position of a Si atom in the first layer of an unreconstructed surface M) are listed in Table 13. As atoms are shown in black and Si atoms in white.

Reports of nucleophilic attack at atoms other than those above have also appeared. A kinetic study has compared the effectiveness of tertiary phosphines and phosphite esters in the catalysis of the cleavage of the silicon-silicon bond of methylchlorodisilanes, providing evidence for the involvement of a stabilised silylene intermediate. The anion of the y-phosphino-p-diketimine (197) has been shown to react with arsenic trichloride to give the phosphino-arsino-p-diketimine (198), in which there is a coordinative link from phosphorus to arsenic. ...
