Only forantion of metallic derive. could be possibly placed in this cats
gory these appear to have the structure (B0)0814 but the Na salts in
their action on 1120 do not act as salts of a strong acid and are instantly
hydrolyzed.Hance in the above system the let structure is so predominaut
that the reactions of the 2nd fora do not realize themselves;this fact

thiophosphites indicate structure (RID)P(8)H; these are sol
in org.solvents and a Rt0H but insol in H20; their solns. are neutral
They are Insol.in agialkaliee and are hydrolyzed by acids and alkalies
yielding Be015,T1iey are vigorously oxidized by Treatment with
standard aq,alo.NAOR they slowly coasume alkali because of hydrolysis
to CROP(S)(0Na)14after this the alkali oonsuntlon becomes so 51CM that
it ts possible to actuallytitrate these esters to thts endpoint. This
is similar to behavior of (R0)00R. Acidification of these Na salts yields
solns. of acidic monoalkyl thiophosphites which are stable for months The
