The addition of arylstannanes to the carbon-heteroatom double bond in the presence of a catalytic amount of a cationic rhodium complex ([Rh(cod)(MeCN)2]BF4) was examined. The reactions of aldehydes, α-dicarbonyl compounds, and N-substituted aldimines with the arylstannanes gave corresponding alcohols, α-hydroxy carbonyl compounds, and amines, respectively. An arylrhodium complex generated by the transmetalation with the arylstannane was probably the active catalytic species.

A rhodium complex catalyzed the addition of aryl- and alkenyl-stannanes to activated aldimines under mild and neutral conditions, affording the corresponding amines in good yields.
THE REACTION OF ETHYL-FORMIMIDATE WITH GRIGNARD REAGENTS: A NEW APPROACH TO ELECTROPHILIC AMINATION
Zawadzki, Stefan
, p. 263 - 268 (2007/10/02)
Addition of Grignard reagents to ethyl-N-(diethoxyphosphoryl)formimidate, 3 followed by aqueous workup and treatment of the resultant diethyl phosphoramidates with p-toluenesulfonic acid in ethanol gives, depending upon the organomagnesium reagent used, the corresponding tosylates of primary or secondary amines in moderate to good yields.The diethoxyphosphoryl moiety remains unchanged upon treatment of 3 with Grignard reagents.Key words: Diethyl-(N-alkylphosphoramidates); Grignard reagents; ammonium tosylates; substitution-addition; substitution-reduction; electrophilic amination.
