The thermolysis and photolysis of various oxazoles, diazoles and triazoles 1 have'been reported (la,lb) to generate labile 1,3-dipoles (nitrenes) z which subsequently rearrange to cumulene structures 3 or react with certain dipolar-ophiles (when present) to yield 1,3-dipolar adducts 4. Z=

Synthetic accesses to formylated photochromic 3,3-diphenyl-[3H]-naphthopyrans (or 2/-/benzochromenes) are developed through classical cyclization between appropriate hydroxynaphthaldehydes and l,l-diphenylpropyne-l-ol and also via substituent Wansfonnations on the naphthopyran skeleton including bro
