The room-temperature condensation of CH3P(OCH3)2 with an equimolar amount of (C6H5)2PCl leads to the new compound (C6H5)2P-P(O)(CH3)OCH3, whereas the related reaction between CH3PCl2 and (C6H5)2POCH3 leads first to exchange of the chloro and methoxyl groups followed by slow self-condensation of the resulting CH3P(OCH3)Cl molecules. When CH3P(OCH3)2 is combined with an excess of (C6H5)2PCl, the product is found to react further with this excess reagent to give (C6H5)2P-P(C6H5) 2. Furthermore, the room-temperature reaction of CH3P(OCH3)2 with C6H5PCl2 leads to condensation products apparently based on the combination of the C6H5(CH3O)P- end group with CH3P(O)6H5P(O)3(CH3O)P(O)- group. The new compound (C6H5)2P-P(O)(OCH2) 2C(CH3)2 was obtained by reaction of (C6H5)2POCH3 with (CH3)2C(CH2O)2PCl, whereas, also at room temperature, only exchange of chloro for methoxyl group was observed in the reaction between o-C6H4O2PCl and (C6H5)2POCH3. At 140°, the reagents underwent exchange and condensation to give what appeared to be a P-O-P bridged structure, [C6H4O2P]2O.
