Nucleophilic addition of CD3O- to Me2BOMe gives the same addition product as the corresponding reaction between Me2BOCD3 and MeO-, as evidenced by the identical collisional activation mass spectra of the products.This is interpreted in terms of exclusive formation of a boron product ion of terahedral geometry.The decompositions of the product involve loss of MeOH and CD3OH and the formation of MeO- and CD3O-.The major decompositions of (CD3)3B+-OCH2CH2XMe (X=O, S, or NMe2) are similar to those outlined above and may be explained by initial formation of (CD3)3B-OCH2CH2XMe.However, there are some unusual fragmentations (e.g. loss of CH3D) which may occur through the alternative structure (CD3)3B-X+(Me)CH2CH2O-.It is suggested the other ambident species may also react with Me3B to form several tetrahedral species, e.g. deprotonated methyl acetate could yield Me3B-CH2CO2Me, Me3B-OC(OMe)=CH2, and Me3B--O+(Me)CCH2O-.The formation of the third structure is supported by the pronounced loss of ketene from this system.
