131$ a R= H 3-b R= P h efficient substrate, reacting with both the methoxymethyl-(product la) and the methoxyphenyl-(product IC) carbene complex in essentially quantitative yield.(The lower isolated yields reflect losses during purification.) Benzaldehyde N- phenylimine (product lb) and the phenylthiazoline (product 3b) reacted with the methoxymethylcarbene complexes with only~ 60% conversion. Even in the presence of ...
