THE PROCESS FOR THE PREPARATION OF A HYDROCARBAZOLENINE WHICHH COMPRISES HEATING WITH AN ACID CYCLIZING AGENT A HYDRAZONE OF A PHENYL HYDRAZINE HAVING A HYDROGEN ATTACHED TO A CARBON ATOM IN THE ORTHO POSITION TO THE HYDRAZINO-BEARING CARBON ATOM AND A KETONE OF THE GROUP CONSISTING OF A 2,3-X-CYCLOEXANONE AND A 2,3-X-CYCLOEXENONE WHEREIN X IS A 3 TO 5 ATOMS STRAIGHT CHAIN SELECTED FROM THE GROUP CONSISTING OF SATURATED AND MONO-OLEFINIC HYDROCARBON RADICALS AND SATURATED MONOOXA-, AND MONOAZA-, AND MONOTHIAHYDROCARBON RADICALS AND WHEREIN A HYDROGEN ATOM IS AVAILABLE AT THE 2-POSITION WHEREBY CYCLIZATION IS EFFECTED BETWEEN THE 2-POSITION OF SAID KETONE AND THE CARBON ATOM IN TE ORTHO POSITION TO THE SAID YDRAZINO-BEARING CARBON ATOM WITH THE SPLITTING OUT OF AMMONIA TO FORM A HYDROCARBAZOLENINE.
