| titleOfInvention | Dihydropentalenyl manganese tricarbonyl, processes for the preparation thereof, derivatives thereof and antiknock compositions therefrom |
| abstract | Dihydropentalenyl manganese tricarbonyl <PICT:0936364/III/1> may be used as an antiknock agent in various types of liquid hydrocarbon fuels. The fuel may contain organo lead antiknock agents, (tetraethyl lead, tetramethyl lead, dimethyldiethyl lead etc.), halohydrocarbon scavengers, esters of phosphoric or phosphorous acids, e.g. tri-b -chloropropyl thionophosphate, and oilsoluble arsenic, antimony and bismuth compounds. Examples of these additives are given. It may also be added to lubricating oils and grease to improve lubricity.ALSO:The invention comprises dihydropentalenyl manganese tricarbonyl of formula: <FORM:0936364/IV(a)/1> prepared by reacting acetylene with a manganese carbonyl according to the equation: <FORM:0936364/IV(a)/2> or to the equation: <FORM:0936364/IV(a)/3> in which Z is a ligand containing a Group Va element (Deming bonded to manganese and n is 1 or 2. Z can be a phosphine, arsine, stibine, bismuthine, amine or a nitrosyl group. Specified compounds are nitrosyl manganese tetracarbonyl, triphenylphosphine-, triphenylarsine-, triphenylstibine-, triethylphosphine-, and triethylarsine manganese tetracarbonyl, tricyclohexylphosphine manganese tetracarbonyl dimer and triphenylphosphite manganese tetracarbonyl dimer. The manganese carbonyl compound may also be of formula XMn(CO)5 wherein X is an alkyl, aryl, alkaryl, aralkyl, acyl, cycloalkyl, alkenyl or alkynyl group or a halogen atom. The reaction then is according to the equation: <FORM:0936364/IV(a)/4> The acetylene is preferably used in excess. The reaction ma be carried out in a solvent, of which many are specified. Temperatures of between 115 and 180 DEG C. and pressures of acetylene from 100 to 5,000 psig may be employed. The reaction may be carried out under a blanket of nitrogen, helium, or argon. Tetrahydropentalenyl manganese tricarbonyl may be prepared by hydrogenating a solution of dihydropentalenyl manganese tricarbonyl in ethanol using Raney nickel as catalyst. It may also be prepared according to the following synthetic procedure: <FORM:0936364/IV(a)/5>ALSO:Films of metallic manganese may be formed on a substrate by the thermal decomposition in a reducing or neutral atmosphere (e.g. hydrogen or nitrogen) of dihydropentalenyl manganese tricarbonyl. |
