Production of arylhalosilanes

Claim 1

THE PROCESS WHICH COMPRISES REACTING A BENZENOID HYDROCARBON FREE OF ALIPHATIC UNSATURATION IN ANY SIDE CHAINS WITH A POLYHALOMONOHYDROSILANE OF THE GENERAL FORMULA RNHSIC13-N, IN WHICH R REPRESENTS A MONOVALENT HYDROCARBON RADICAL FREE OF ALIPHATIC UNSATURATION AND N IS AN INTEGER OF FROM 0 TO 1, AT A REACTION TEMPERATURE OF FROM 150* C. TO 420* C., AT LEAST A PORTION OF THE REACTION MIXTURE BEING IN CONDESED PHASE; IN THE PRESENCE OF A SILICON-BORATE COMPLEX SELECTED FROM THE GROUP CONSISTING OF (1) THE REACTION PRODUCT OF A SILANE OF THE GENERAL FORMULA R''4-A-BHASIXB WHERE EACH R'' REPRESENTS A MONOVALENT HYDROCARBON RADICAL, EACH X IS SELECTED FROM THE GROUP CONSISTING OF ALKOXY AND CHLORINE A IS AN INTEGER OF FROM 0 TO 1, B IS AN INTEGER OF FROM 10 TO 4, AND THE SUM OF A AND B IS NOT GREATER THAN 4; WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF B2O3 AND COMPOUNDS OF THE GENERAL FORMULA (R''O)XBR3-X WHERE R'' IS SELECTED FROM THE GROUP CONSISTING OF MONOVALENT HYDROCARBON RADICALS AND HYDROGEN, R S AS DEFINED ABOVE, AND X IS AN INTEGER OF FROM 1 TO 3 INCLUSIVE; AND (2) THE REACTION PRODUCT OF A SILICON COMPOUND SELECTED FROM THE GROUP CONSISTING OF SILOXANES AND SILANOLS WITH A COMPOUND OF THE GENERAL FORMULA RYBY3-Y WHERE R IS A MONOVALENT HYDROCARBON RADICAL FREE OF ALIPHATIC UNSATURATION, Y IS A HALOGEN ATOM AND Y IS AN INTEGER OF FROM 0F TO 3 INCLUSIVE; WHEREBY TO PRODUCE AN ARYLCHLOROSILANE.
