A series of 2-alkynyl 2-diazo-3-oxobutanoates, when treated with a catalytic quantity of rhodium(II) acetate, were found to produce furofurans in good yield.The reaction proceeds by addition of a rhodium-stabilized carbenoid onto the acetylenic ?-b

treatment of a series of α-diazo alkynyl substituted ketones with rhodium (II) carboxylates results in the formation of vinyl rhodium carbenoids. These species undergo further cyclization onto a neighboring carbonyl group to produce furans.
