The development of a method that uses molybdenumhexacarbonyl [Mo(CO)6] as carbon monoxide (CO) surrogate for the palladium‐catalyzed reductive cyclization of nitroalkenes into indoles or thienopyrroles is reported. Several types of nitroalkenes could be transformed into the desired products in excellent yields and in most cases with complete regioselectivities and higher yields than those previously
