Dehydration products of 2-methylisoborneol

2-Methylenebornane and 2-methyl-2-bornene have previously been identified as dehydration or degradation products of 2-methylisoborneol (MIB), a compound responsible for taste and odour problems in various water environments. Previously, the identification of these products has been based on mass spectral analysis only. The dehydration of MIB under a variety of conditions was reinvestigated and the products fully characterised by 1H and 13C n.m.r. and GC-MS. Comparison of EI mass spectra of the dehydration products of MIB with those published previously indicate that earlier assignments of MIB dehydration products are incorrect. 2-Methylenebornane and 2-methyl-2-bornene have previously been identified as dehydration or degradation products of 2-methylisoborneol (MIB), a compound responsible for taste and odour problems in various water environments.

Reactivity of phosphonium diylids with aldehydes and ketones

Non-stabilized and semi-stabilized phosphonium diylids of the type (C6H5)2P(CHR)(CHLiR) (5) show a greater nucleophilic reactivity toward carbonyl compounds than the corresponding monoylids (C6H5)2P(CHR)(CH2R) (8).Thus diylid 5a reacts readily at room temperature with sterically hindered ketones such as fenchone or di-t-butylketone.However, the residual negative charge in the intermediate adduct 13 slows the decomposition to Wittig products and is probably responsible for the observed changes (generally enhancement) in the E-selectivity in the case of non-stabilized as well as semi-stabilized ylids.
