Further derivatives of 10, l l-dihydro-, 5H-dibenzo [a, d] cycloheptene were prepared as potential antidepressant agents. 5H-Dibenzo [a, d] cyclohepten-5-one and the corresponding 10, ll-dihydro ketone were allowed to react with a variety of organometallic reagents to give tertiary carbinols, from which additional compounds were prepared by dehydration and reduction procedures.
