Dichlorophosphines esters

Biphilic Reactions with Carbonyl Compounds.—The dichlorophosphine (34) undergoes a standard chloromethylation when heated with paraformaldehyde, and a good yield of the phosphinic chloride (37) is obtained. At temperatures below 100 °C, the ester (38) is isolated, and the authors discuss, somewhat speculatively, the mechanism of the reaction see Scheme 3. [Pg.53]

Mercaptoacetic acid esters with phosphorus trichloride gave the thiophosphoro-dichloridites (51) which on heating cyclised to 1,3,2-oxathiaphospholanes (52) with traces of oxygen the more nucleophilic analogues, e.g. (53), rearranged at room temperature to the thiophosphonate derivatives, e.g. (54). The first ferrocene-diyldiphosphonite (55) has been prepared by two routes, from the ferrocene-diylbis(dichlorophosphine) and from the ferrocenedilithium compound. ... [Pg.85]

Benzaldehyde condenses at ordinary temperatures with phenoxy-dichlorophosphine, and methoxy- and ethoxy-dichlorophosphmes in the presence of acetic acid, forming respectively phenyl, methyl and ethyl esters of a-hydroxybenzylphosphinic acid ... [Pg.142]
