This subclass is indented under subclass 466. Processes
wherein a silicon-containing compound is halogenated.
Subclass:
477
This subclass is indented under subclass 476. Processes
whereby a silicon to halogen bond is formed.
(1) Note. Included herein are those processes wherein the
silicon to halogen bond which is formed is by the replacement
of a halogen bonded to silicon by a diverse halogen.
Subclass:
478
This subclass is indented under subclass 466. Processes
whereby a silicon to carbon bond is formed.
(1) Note. Included herein are those processes wherein the
silicon to carbon bond which is formed is by the replacement
of a carbon-containing radical bonded directly to silicon by
a diverse carbon-containing radical.
Subclass:
479
This subclass is indented under subclass 478. Processes in
which carbon to carbon unsaturation is reduced by the
addition of a silicon hydride to the adjacent carbon atoms
with the subsequent formation of a silicon to carbon bond.
Subclass:
480
This subclass is indented under subclass 478. Progress
wherein a magnesium-containing reactant is utilized.
Subclass:
481
This subclass is indented under subclass 478. Processes
whereby the silicon to carbon bond which is formed takes the
place of a silicon to hydrogen bond.
Subclass:
482
This subclass is indented under subclass 465. Compounds in
which both silicon and carbon are bonded directly to the same
oxygen.
(1) Note. Examples of compounds provided for herein are:
