摘要:
The present invention provides a process for preparing a 1,1-disubstituted ethylene derivative of the formula ##STR1## which comprises reacting lead with a carbinol derivative of the formula ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, X, Y, m and n are defined in the specification. The reaction is conducted more advantageously in the presence of a metal having higher ionization tendency than lead.
