Compounds with Ge—O—P Linkages

Oxidation of ethylgermylphenyl phosphine with oxygen at room temperature yields Ge-O-P linkages, and with bromine the Ge-P linkage is also broken. 

If germyl phosphine is heated in oxygen, an eight-membered ring compound is obtained (9.308), and with water, phosphine is evolved (9.309).
