AbstractWe prove that the theory of the extensional compositional truth predicate for the language of arithmetic with Δ0-induction scheme for the truth predicate and the full arithmetical induction scheme is not conservative over Peano Arithmetic. In addition, we show that a slightly modified theory of truth actually proves the global reflection principle over the base theory.

Reactions of aquacobalamine with dimethyl and diphenyl phenylphosphonite and with methyl diphenylphosphinite lead to neutral complexes in which the partially hydrolyzed an ionic ligands [PPh(OR)(O)]- (R = Me, Ph) and [PPh2(O)]- are P-bonded to the cobalt(III) ion of the cobalamine moiety. Hydrolysis of the prochiral phosphonite already coordinated to the chiral cobalamine leads to two diastereomers which are formed in different yields. This optical induction is seen in the 1H and 31P{1H} N M R spectra.
