Carboalkoxymethyl compounds

In order to produce free alkyl acetates, the alkoxyacetyl complexes 5-7 must first isomerize to carboalkoxymethyl compounds... [Pg.282]

Intermediates occurring in the acid-promoted isomerization of an alkoxyacetyl complex, CpFe(C0)2C0CH20Me (5a) to its carboalkoxymethyl compound CpFe(C0)2CH2C02Me (11a) have been observed by IR. Upon addition of acid to 5a, its IR terminal v (2025,... [Pg.288]

We found no evidence for isomerization of the a,6-dialkoxy-alkylidene complexes CpFe(C0)L[C(0Et)CH20R] (9,, 15) to alkylated carboalkoxymethyl salts CpFe(C0)L(CH2C(OR)(OEt) ) under ambient conditions. Indeed the solution chemistry of a,6-dialkoxyethylidene complexes parallels that of a-alkoxyethylidene compounds CpFe(C0)L[C(0R)CH3]+, in that 9,14,15 quantitatively revert to 5-7 upon treatment with excess io3i3e in CH2C12. We did, however, prepare samples of the ethylated carboalkoxymethyl... [Pg.289]
