SELF-IMMOLATIVE SYSTEMS
The present invention is concerned with self-immolative recognition and/or responsive systems for electrophilic compounds, especially alkylating agents, which systems may comprise disclosure or detection of the alkylating agent. The present invention is especially concerned with non-protic triggered self-immolative systems, molecules, and methods, and in particular for detection of non-protic electrophilic agents, and especially alkylating agents, for example alkyl or benzylic halides, which may be found in pesticides or fumigants, or chemical warfare agents.

Stable hydroformylation catalyst for preparation of high N/Iso ratio aldehyde product
A new stable, catalytically active, tetradentate organophosphorus modified rhodium hydroformylation catalyst has been discovered that is capable of producing aldehyde products with a high linear/branched product ratio from linear olefins. The tetradentate organophosphorus modifier is a tetrasubstituted 2,2,2,5-tetramethyl-1,1:4-1-terphenyl, whereby, each methyl group has one hydrogen substituted by an R, R-diorganophosphine moiety. The R, R may comprise aromatic, alkyl, arylalkyl and alkylaryl groups. The precursor 2,2,2,5-tetramethyl-1,1:4,1-terphenyl hydrocarbon may be prepared from para-xylene and toluene derivatives.
