note that if a grignard reagent (such as rmgbr) is used, the reaction with an enone would instead proceed through a 1,2-addition.

*reaction with a second equivalent of r-li to r-cu gives the lithium diorganocopper compound.
reaction with a second equivalent of r-li to r-cu then gives the lithium diorganocopper compound.

thus, reaction with sodium hydroxide gives sodium dihydrogen phosphite and disodium hydrogen phosphite, but not trisodium phosphite, na3po3 as the third (p-bound) hydrogen is not acidic.

for example, reaction with sodium sulfide produces the brown/black tin(ii) sulfide::sncl2 (aq) + na2s (aq) → sns (s) + 2 nacl (aq)if alkali is added to a solution of sncl2, a white precipitate of hydrated tin(ii) oxide forms initially; this then dissolves in excess base to form a stannite salt such as sodium stannite::sncl2(aq) + 2 naoh (aq) → sno·h2o (s) + 2 nacl (aq):sno·h2o (s) + naoh (aq) → nasn(oh)3 (aq)anhydrous sncl2 can be used to make a variety of interesting tin(ii) compounds in non-aqueous solvents.
